Looking at an old beat up Burny. Unsure of its age. My googling tells my it might be late 70's early 80's as it has the Les Paul script on the head stock. No serial info
First impression is often a letter, sometimes on its side. Second one looks like maybe a 5, so 1975. Made by Terada. Here is my 1975 FLG with Godzilla approaching.

After staring at the beginning of the serial number, I think I see "77" in there, sort of subtle. Maybe my imagination, but it would fit the year spread you quoted. Al
Another vote to 1975 made as far as 1978 and 79 are Tokai made. Fernandes F copies made in 75 and 76 have a serial starting by 5 and 6and 1977 FLG have stone logo turners
