The Duprat 5-pin hollow steel crank, sort of octagonal section, weighhed 3 gam (0.1 oz) more than the comparable TA cyclotourist right crank. I think they were 159 and 156 gm, respectively, but can't put my hands on that list right now.

Weren't the hollow armed steel cottered cranks just as light as Al alloy cotterless? I hefted a '50s Durax (?) octagonal armed crank and although I didn't weigh it, it felt about the same as Al alloy Campagnolo Record cranks to me weight wise.
