Eko solidbody 8-string mandolin and an Eko solidbody 12-string mandolin. The latter is essentially an octave 12-string guitar (I used to have one myself), almost certainly influenced by the now legendary Vox Mando Guitar, and usually tuned a whole octave above (modern) 12-string guitar tuning.
I'll let you know what these Eko mandos fetch on eBay when the auctions end.
