Hey Spud1950,
I don't have a positive ID for your guitar, but I'm willing to take a guess.
That plastic compensated bridge was used by Guyatone and Zen-On.
The only time I have seen that tailpiece is on a Zen-On.
The pups look Zen-On.
So, without further information, I'm guessing Zen-On. Here's a picture of a 1966 Zen-On Zes-170 that I believe has close to the same tailpiece as your guitar.
