Have a Goldstar Sound (serial L25181) and want to try confirming model and age. Got my own opinion, but will just post the details here and see what others think.
Solid colour, so problematic determining how many pieces the body comprises, but the control cavity has the sequence "7 15 68 V" stamped inside. Pots have the expected "M250" and "55" codes, and selector "3D1". Neck pocket is stamped "V".
Neck is single piece maple with rosewood board, with the sequence "7 17" stamped on the end, and "0 7" on the bottom.
Pickups are stamped "V I".
Tuners are stamped "Deluxe".
