Durax chainsets were available during the 1930's, and were standard equipment on some high-end British bikes, such as the Baines WRB Championship model and WRB Valkenburg Continental.
Two models of Durax 3-arm cranks are also listed in the 1937/38 Fonteyn & Co catalogue, one of them being the fluted crank model. As a matter of interest, this catalogue also lists the Duprat hollow cranks.
Fonteyn & Co imported Continental (which at that time, mainly French) lightweight accessories into England before and after the war.
