I have the same Maillard freewheel that came off a set of Campy hubs and Ambrosio Montreal tubulars as well as a few Regina corn cobs kicking around... I don't find them to be all that useful when you run a 42/52 and like to climb hills but bet they are good in Florida.
Was also stripping wheels today and found a few nice freewheels including some decent UG models which I think you are fond of.
Most interesting was a Suntour Alpine freewheel today with a 13-30 but with some really tight spacing between the lowest cogs and wider spacing at the bottom... definitely a mountaineering cluster.
Spent the evening cleaning and polishing bits here and will post some pics tomorrow... the Zeus 2000 group I have is almost complete and is looking very bright and shiny... especially the hubs.
