Did it go by contract number or serial number within a specific manufacturer.  Mine is Collins SN 16xx.

The fuses were changed from 1 (early) to 2 (later) to add a B+ fuse.  What is your contract number?

I have a Collins R390a.  It has two fuse holders on the rear panel and I was
told that at some point this was changed to one fuse only.  Does anyone know
about what serial # this change was made?
