It looks like the chamber was pretty harshly ground. Chamber stamps are very much shallower than you would expect, and when removed with care the only way you can tell is by minute differences in surface unevenness which show up by specular reflection. The grinding here is easily enough to obliterate a 1920 property stamp.
