This is simply an old Larsen sandblast. I can see the ‘handmade in Denmark’ stamping, but nothing that says Copenhagen. I do see an “IPED” on the shank bottom, near the stem, but what does that mean? It’s large, at least a Grp. 7, and the blast is deep and interesting. A true character blast. The condition of the bowl is excellent, but the stem is acrylic, with some tooth chatter (I can reduce that with polishing) and I think it’s likely a replacement.
6.25” long, bowl 2.35” tall. Weight: 2.5 oz., 71 grams.
