Here's a new-to-me model 7-5 courtesy of Mr. Tunefink. Pictures also courtesy of same. Seven spacers and Heiser sheath. Late '50's maybe. And, yes, I did notice the cracks and checks but I have to say that's a big part of what appealed to me actually. I think the knife has a helluva a lot of character. Anyway, very happy to add it to the small but growing herd.
