Raoul asked about block chain being made and used up until the 1960s. The context is real block chain with a solid inner linking piece, two side plates etc. and not a roller in sight.
>From my own experience I think block chain was even sold new in the 1960s. Keep in mind this would be used by tradition minded sprinters only. My 1959 Frejus track bike had a Regina block chain, and Campagnolo 1" pitch cogs. The Frejus catalog skips the chain in the equipment listings, although I gather Frejus favored Everest cogs and chains. I tend to think the chain was original on the Frejus because it is darn hard to wear them out.

I suspect Regina was the last block chain made new.

Per the 1939 Oglaend's catalog available from Velo-Retro a Diamond Block Racing chain was $ 4.80 wholesale and a Diamond No. 61 Roller chain was $2.50.

Anyone have later catalog entries for block chains?
