Has to be one of the last Gneco Teles with small neck plate?
It has a one piece neck with the truss rod adjustment at the heel, whereas my Gneco Tele had the truss rod adjust at the headstock and 3 piece laminated neck. Unfortunately I never had a clue what year it was from, and neither did anyone else.
This Tele is right where they were transitioning into accurate clones which occurred by 77. Also the Gneco logo was gone in 76.
I personally doubt whether there were star tuners on Greco Fender clones after 76, so I reckon it could be 74 like you say, or maybe 75? I've seen a couple of earlier ones claimed to be 73, and they had a strange look to them in general with different looking pickups and tuners.
