Looks great. If the durn rear brake bridge weren't so low, you could fit some huge tires in there. Still good room up front too.
The 1984 610 at least was sold new with 27" skinny tire wheels (I got mine new), and the radial clearances front and rear were scant with that setup.
There's another wheel constraint with these frames, that the distance between the chain stays leaves precious little clearance for a 650x42 mm tire, based on a test fitting. 38's are about the upper limit. On my 610, I can comfortably fit SKS 45 mm fenders with 700x28c (Ultra Gatorskins), but it's hard to avoid rear fender rubbing with 700x32 Pasela.
