An interesting bike of the period. When the modest extra cost of Campagnolo forged ends was just too dear in the overall consideration.
I like the look of the bike very much.
Price / value is I think very difficult to assess.
To one who has a urgent desire for one, probably pretty strong in a bidding situation.
Open market? Tough, very tough.
Size "looks" 22" center to top, probably a 'Square" bike with a 22" top tube too.
