atmo crankshaft wanted

Hi, I'm after an atmo crankshaft if anyone has one for sale.

I have one in my own spares stock if you get 100% stuck, but I had planned to build it into an engine...I am currently looking for other bits.
I know of an engine in west London too that would have it in, cannot Rats or JL engineering help?

No Atmo cranks ..very rare item ...

Is there something special about them or are they std PRV oddfire cranks?
Maybe I don't have one....?

Thanks for your replys but I may have it sorted, Cheers.
