On Italian ebay, there is a set of very early cotterless Magistroni cranks for sale. It looks from the gap between the crank and the spider that this was meant for use on a bike with a chaincase. They are however neat cranks and would make a nice addition to somebody's collection.
I have bought from the seller in the past and he is dependable from my experience.
