Both expanding and contracting. The 1967 Paramount, 1982-ish Ron Cooper and 1986 De Rosa stay. The Russ Denny-built Fuso goes. I'm up in the air about the 1994 Trek 520, but it probably goes. The late 1970s Eisentraut A gets repainted and built up and, unless it rides like a dead dog (which it won't), it stays. My brother-in-law
s early 1970s Gitane Tour de France gets refurbed adn out of my basement. My friend's 1975 Eisentraut Limited gets sold and out of my garage.
I have more or less embarked on a quasi-refurb. I've had an old Bianchi frame since I was a teenager - it has been reliably ID'd as a 1961-ish Competizione, the lowest end of the Reparto Corse/Columbus tubed frames. It has a red rattle-can paint job that was done by some idiot many, many years ago.

It has a bottom bracket that is so frozen it acts like a vestage fo teh last Ice Age and a seatpot that is all but welded inside the seat tube. Once I solve those issues, it gets a respray (not celeste - not an option on this model; it will probably be blue, which was an option then) and gets rebuilt with the period-appropriate (meaning not as it was originally built, but stuff that fits the era) parts I have been accumulating. This one will not get ridden an lot, if for no other reason than the low gear will be about 48x24 (Campy 151 bcd cranks and Record, not NR, rear derailleur and Gran Sport push rod front derailleur will do that). But it will make a cool display bike.
