Four 4 Digit Serial Number Examples

[eborej]

Do you happen to have production and switch codes? These 4 digit serial numbers seem to not be linear. I would love some dates that we can pin down for serial numbers.

Here are the stamps on the neck & body for 0619. I'll have to get them for the other TST-60s. What are switch codes?

Awesome. And the selector switches on most of these in this period witl be Matsushita switches which have a date code on them on the side.

Also very important are pictures of the headstock decals/logos. They changed several times in the 1982/83 transition, so that can help as well.
