I don't seem to have the time these days to do much renovation work on the pre 1960 parts which I know some of you look out for. However, I have managed to list just a few items on Ebay this evening, including a mid 50s Gran Sport rear mech, some Brampton B8 pedals, and a Stronglight/Simplex double chainset. The item number for the chainset is 390068146982, and you can then find the rest by viewing sellers other items.
