I picked up a slightly older Sankyo to gain some experience with something other than a Nishijin. It came with a damaged upper ball tray and I saw the Comet II front panel & tray on eBay today & it would be an easy fix to swap it. But the question is are the holes for the ball feeds etc. the same between the Comet II & the slighlty older machines like the Nishijin units are? The Sanko is from around 71-73.

I'll try to post a picture of the machine, there's some kind of hang up between Windows & the picture posting software on this PC.

Thanks,
Mark
