Teisco serial number dating
A 7 digit number example - C5030567 - translates, 5 = 1995, 03 = 3rd month [March], 0567 = 567th guitar built in March 1995.
An 8 digit number example - C03114373 - translates, 03 = 2003, 11 = 11th month [November], 4373 = 4373rd guitar built in November 2003.
- Cort serial numbers are denoted with a C prefix followed by either 7 or 8 digits.
I'm not sure what year the changeover occurred but using the formula it will be easy for you to tell.
There are many variables of numbering through these years and between different models and are broken down into 3 categories, stickers, plates, and the impressed numbers that follow the old school style detailed above.
See the Factories heading a few paragraphs down for little info on guitars produced elsewhere.
In cases where generic non model specific plates are used the 4 digit number is just the consecutive number of that plate which could have made it on possibly 10 different models.
- JEM plates are 6 digit and the first 2 digits is the production year while the last 4 is the consecutive number JEM built from inception. Except for the very first batch of 90' UV plates that began 00, UV plates are also dated by the first 2 numbers. A Universe plate 912787 would denote a production year of 91 and the 2787th Universe built.
If you're trying to figure out what model something is from the serial number, figure out what year it is then go to the catalog library for the corresponding year [or year before or after] to find the model.
Some models will never be found in the catalogs, that's just the way it is.
