can't ID a specific model, but according to the decal it should be Columbus SL or SP (what size seatpost?) and seems to have Prugnaut lugs (EDIT: in the CR Main site that style lug may be a cast item made for Rossin in the style of a Prugnaut) so for $68 you stole it despite the scratches and lacking fork. Make sure the fork wasn't tossed cause the bike was front-ended: check for any ripples near the headlug sockets.
The paint plus single WB bosses and that style of decal probably places this in the early-to-mid-eighties and I'd weight it toward the "early" end, but somebody with better researching skills may get it closer.
Check the brake bridge for a Ten Speed Drive "little rider" panto, tho I have a feeling this might pre-date the TSD import era.
Another EDIT: similar paint/graphics shown on a purported 1980's frame, but that "Ghibli" has fancier details to yours, may be about the same year, tho.

Does the seat post come out?

Very nice catch! My guess would be '84 ish Rossin Record

Thanks, on to repaint
