Thanks to both for links and advises, need to see closer what is exactly the adaptall mount and how costs the K adapter, I guess it only works in K mode ?
Well this is the risk on e-bay, even deals that look good can be a waste of money because you cannot test the lens.
I have a shop not far from home where they have a bunch of vintage cameras and lens but few k-mounts and btw I find their prices generally not friendly at all, they would buy set of nice used lenses for very low prices and resell them with almost 200% benefits... you certainly have much better deals in the U.S.

Ok thank you, so it is probably not made in China...
