T-Mar has been pretty active here in the past few months, and he's a genius but I don't think even a genius can decipher the Holdsworth/Holdsworthy serial number "system"...if you can call it that!

If T-Mar has a handle on it and can share that knowledge, we will be even more grateful.
Supposedly, Nick Kilgariff at one time was taking serial number-tracing requests from Holdsworth owners, but got out of that "business" when it got to be too much for him.

There was a forum member here: Skip Magnuson that was compiling a database, but he has disappeared...it must be a cursed enterprise...
