G&L tuners

I had a question about some tuners I'm getting ready to sell.
I am pretty sure they are for a USA G&L but I thought I'd confirm that before writing my auction/marketplace description.

here are some pics:
...they are stamped "japan" , any info is appreciated ( era, gear ratio, etc.)





thanks in advance,
Elwood

They are probably from one of the early Japan Tribute models.

As I've never seen any tuners on an USA G&L having that hole for fixation with a screw. The always have a pin.

Thanks Miles,
I couldn't quite remember where they came from and the japan stamp had me suspicious that they weren't meant for a USA model, but I've never had a japanese tribby...hence my confusion.
I must have bought the set on ebay in one of my manic G&L collecting episodes.

cheers,
Elwood
