I don't know this one. If it is 6.5 inches across centres it is probably British. Does not look like Williams, Phillips, Nicklin, Chater, or BSA, the only double fluted British cranks I remember were BSA.

Re:

Hi Keith, 6.5 inches yes. English thread on the pedals. It is extremely light, steel and double fluted. Got me mystified.

Re:

Consensus so far seems BSA made for Grubb. Would like to find a chain wheel crank but clutching at straws probably.

I recall similar ones on my old trike in 1968. I think that was a TA 5 pin cottered set, if I remember correctly. It was a b***r to set up and had smaller OD cotter pins than standard english ones.

Thanks Dodge. Still not seen anything similar to it. 5 pin would be great if I could find one.
