What is the Teisco Serial Number / Date Chart?

The chart is a listing of model numbers going downwardly the page and a list of series numbers going across the page. Guitar models take their respective serial numbers marked on the chart. Above the serial numbers is the estimated production dates for those serial.

What Can the Nautical chart Tell Us?

The chart can provide a lot of information, such equally the following;

� Determine when your Teisco was made based on the serial number;

� Identify what other guitars models were made when your guitar was made;

� Determine how many of each model was made;

� Come across how ofttimes each guitar was made;

� Determine which models are rare and which are common;

� Place the sequence of when guitars were constructed;

� Approximate the product output of Teisco manufacturing plant during the series number era;

� Decide the total number of Teisco guitars that were made during the serial number plate era.

At that place are some interruptions in the data for some of the above, but the accuracy is probably the best that will ever surface. The chart volition exist revised and expand as more information is discovered and confirmed.

The chart also gives the states a management on how to start to study each model and a reference betwixt other models.  Hence trends in product techniques and hardware used can be compared. A lot of information on this spider web site has been discovered from the trends in this chart.

How the Chart Came Into Existence

The Teisco series nautical chart was reconstructed from serial numbers off Teisco guitars that have surfaced on the internet since 2007. The numbers were recorded from as many possible sources that could be found.

It all begun with an eBay list that stated �There might have been just 500 Spectrum v guitars always made. Could be as many as 2000. No 1 really knows.� Someone wanted to know really badly. (And at that fourth dimension they didn't even have a Spectrum 5.) Then what if someone recorded every spectrum five serial number they could detect and see if it linked upwards?

Then the Teisco Serial / Date Chart project was started and several months of research later it became evident that some things did not link upwards. The numbers were all over the identify. From that point it was decided that all serials numbers from all the models needed to be nerveless. Then mayhap it could finally be adamant exactly how many were made. Several searches were done on the cyberspace to determine a complete list of Teisco models. The trouble is that a lot of the models did not have whatever pictures. It was determined that some of the model numbers were not even Teisco models on those original lists. This project took years of enquiry just to determine what was or was not a Teisco, and also, what each model looked like. As fourth dimension went by, missing models were added and not Teisco models were removed. Hence the most accurate and consummate list of Teisco models was developed.

Equally the Teisco models were being recorded the serial numbers were archived in such a way that they could be recalled later to enter them into the chart. These numbers were slowly all mapped onto the chart. The calibration was determined by limitations of excel and a size that could exist viewed on the screen, such that any patterns could exist observed.  And so the guitars were grouped in blocks of x,000. So if required, all the guitars in a given block could be viewed in the archived files that were logged. (Note the archived files will not published.)

As the chart started to have shape, patterns started forming very early on. It became very apparent that Teisco was actually very diligent with there serial numbers and model numbers. In fact the serial numbers flowed very consistently and changed the way that Teisco guitars were considered to be built. The original merits,

that Teisco would simply employ any parts on hand when building guitars in their factory has now been proven wrong.

The chart clearly showed when models were manufactured in relation to other models. By looking at a grouping of serial numbers of a model, it was determined how the evolution of the model occurred. (ie The hardware changes etc.)

The information provided from the chart is something that no vintage guitar collector ever idea would exist possible to obtain. A large part of the hidden history of Teisco is in that chart. Information technology has enabled united states to study and understand what the company produced and what changes happened in its production history. This is data that has been lost for decades. To date, information technology has provided the almost accurate insight into the history of one of the largest guitar manufactures of it�southward time. This information is more than than any other guitar researcher / writer has been able to produce in the last xxx years on Teisco guitars.

Anyway dorsum to that start question. Well we have a pretty good idea of many Teisco Spectrum 5�s were made. We want to be very accurate, but nosotros need more serial numbers to narrow the spaces between the serial numbers we have. With time, these gaps will be filled in to such a point that the chart tin be recalculated in increments of 1,000 instead of 10,000.  It volition then exist possible to accurately approximate how many of each model was made. Only till then, go along sending in your model and serial numbers. If y'all take a Teisco, you can assistance. Come across Aid Re-Discover Teisco .

How Dates Were Linked to the Serial Numbers

The initial unpublished nautical chart was undated and was useful to construct a map of when models were made in relation to each other. It was not able to plant a link betwixt when each guitar was manufactured, based on the series number.

At first, dates from original owners were recorded when they bought or received a new Teisco guitar. Merely this seemed inconsistent. Mainly because people forget when they got the guitar and who knows how long it was in a store before it was sold. At that place were besides many unknowns when working with these dates. Only it did provide a good reference point afterwards as these serial numbers needed to be manufactured before these dates. So these became checks points subsequently on.

So then some Bennet Bros catalogues were cross referenced to attempt and determine when particular models were made and when they were featured in catalogue. Over again the nautical chart and this data did not match. Guitars models appeared in catalogues for many years after they were built, due to depression sales or over purchasing of certain models. There was not a articulate link to production. A lot of these catalogues used stock photos. Hence a slight hardware alter may have occurred simply the photos in the catalogues stayed the aforementioned. This prevented an exact link between actual serial numbers and these catalogues.

Finally ane WMI catalogue surfaced and these were very skillful. Firstly these catalogues were dated with the month they were printed. These were besides printed in Japan . So they may have accompanied the guitars in the shipments. These were updated with new hardware changes and the release of new models. By mapping each guitar that was in that catalogue, by the exact hardware and the earliest production run of each featured guitar, gave the possible serial number range at the fourth dimension of printing the catalogue. By then looking at the first product run of the latest model produced in the catalogue, would be the serial number at the fourth dimension the catalogue was printed. The catalogue could not have been printed earlier the latest model was fabricated. This was the key link between the dated catalogue and the serial numbers. Future WMI catalogues were and so mapped. The average guitar production was calculated betwixt each outcome of each catalogue and was adamant to be fairly abiding monthly average. Which meant the catalogues and serial numbers corresponded.

The chart dates were then checked against dates provided by owners and other printed catalogues, to ensure that the first batch of any model didn�t post date the relevant catalogue. This confirmed the link between the serial numbers and the catalogue dates were very shut to accurate.

Yet, there is ane inaccuracy in the dating method. This existence the time between when the last guitar was ready to be featured in the catalogue, and when the catalogue was actually printed. There could have been a slight filibuster for artwork blueprint and actual printing time.  This time is unknown and has been assumed every bit nil for the moment.

And then Where is the Chart?

The chart is about 80% to 90% complete. There has not been a lot of support or information come through on the Help Re-Discover Teisco site, and then at this time the chart will not be published.� Withal information from the chart is being used to prepare this web site.
