I wouldn’t waste any more time on the Rossin you posted above. It’s got a mish mash of parts someone slapped on it. You could drop $500 trying to clean it up, and it’d still be a mess.
Go find the one below on ebay. It’s been there for 6-7 months and asking 1150. Owned by a bike shop. 10 Speed Centaur, respectable, with Mavic Open Pros. Chrome fork, chain stay and the good dropouts. You never stated what size you need. This one states size 59cm. I’d want to know the top tube measurement. I'd speculate the bike shop could swap the seat post, stem and bar to something more vintage looking if wanted.
