Ok, so what do each of the digits mean? For example, B123456 how would this "made-up" serial number be decoded?
Chris & Kirby Serial #'s...
Hello Chris.
I hope all is well w/ you & your's. It was good talking w/ you.
Here is a link to an old thread I posted in. If you skip down to Post #3. This applies from the present model back to & including the Heritage I.
I've not yet learned the 'exact coding' for the models prior to the Heritage. A lot of times you can find a 'manufacturer's clock' that will give you a close approximate. However, that only started to be incorporated onto some parts, in the early sixties, I believe.
Talk again soon, Chris.
Cheers & hagd/n all,
Bill
