Hey All, I have been trying to hunt down the production year for a LP my father gifted me years ago. It's a custom, and SN is 615724. According to everything I can find this indicates it’s as early as a 1970 or as late as a 1975. To my understanding this also excludes it from being a 1973. Checking the numbers on the potentiometers shows they are all from 1977. The only other identifying characteristics are that I know it to be a mahogany neck and someone added Schaller/Gibson flip out tuners, most likely added in the 80's. If there is someone who can help me narrow down the year when this was built that would be awesome.
