I said I wouldn’t buy this but I did. As you would expect with a Charatan, clearing the oxidation was a job. Me thinks this is a Rueben (inedible)? It’s quite small, 24 grams (as shown in the ‘51 catalogue). I’m not sure though. Very small pipe, two digit #, no letters…Rueben? Late Rueben? I got this for about 60$. I’m not sure why no one bid on it, apart from the oxidation. But oxidation doesn’t stop people in Japan from bidding on all kinds of other pipes, even other flashier Ruebens. This one kind of flew under the radar. Well, I think it was a score so…I’m happy.
