Just got this BBB Silver Grain model 607 billiard really cheap off eBay. The stem sits strange. Would this have had a trim ring? All the similar models I’ve found online do not. Maybe the stem has been replaced at some point. I wonder if i could sand the stem down to where it mates up nicely, The bit is broken so it wouldn’t devalue it. I’m not interested in having a collector’s piece just a good smoking (and good looking) pipe.
