I have K22 #K44958, before the introduction of the CM. I was told by the seller, who owned it since about 1950, that the dealer returned a small group of them, new, to the factory to be shortened. It letters as 6", SWHF has no records of it, and there are no return markings. The work looks like it could be factory, however.
Question - Is the presence of the lines on the rib under the sight definitive proof that the work was not done at the factory?
