This is the same piston as my other one, only it is rescaled so that it would possibly work in stainless steel. As a "side effect" the price got really high, but Im uploading it anyway. Its just about 43mm across one side, other than that its almost identical to the smaler one except a few areas have been hollowed out to save material.
