Hey all, just curious if anyone has seen one of these 6309's before. Just picked it up as an eBay project. I've gone poring through the catalogs and can't find anything like it. Serial number is 604735 (assuming the caseback is original); I've looked in all of the catalogs in 1975-77 and 1985-87 and came up with nothing (I'm guessing this was 80's just by the look). And I haven't been able to find anything similar on eBay.
