Welcome.
There’s no pic. On my iPad anyway.
The further you get from 1972, the smaller the volute. By 1974 the K-zoo LPs had what I call a "vestigial volute," very small. But this looks like a stickered serial with gold lettering. The "Made in USA" looks like it may be peeling. However, given the size of the font and that it looks like the serial has been heavily oversprayed with clear coat, obliterating the indentation in the finish, this is an odd bird. Could be a break and refin where the luthier decided to highlight the serial and "Made in USA" so that it would stand out under the smooth finish.But, the guitar has no volute to the back neck/headstock? I can see where he might think it was a 68 with the serial # 503xxx though. The post 70 “Made In USA “ stamp definitely puts it past the 68 range and beyond.
