Name those Cranks......

Ola friendly retrobikers
Bought me a set of super cheap cranks on ebay.
Haven't received them yet but even when I do I don't think they'll be much of a hint as to the make, and thats where you lot come in...
So heres the pics from the seller, anybody recognise these bad boys

They look pretty similar to a pair of Grove Innovations Hot Rods I had years ago?
