the size is either a large Grp. 3 or a small Grp. 4. The condition is very good with only a touch of wear on the rim. There is the BBB stamping on the shank and also on the silver ferrule, which may account for the absence of the BBB logo on the stem (which is mark-free, incidentally). Also, and I just noticed this, it was part of a 7 day set as “Tuesday” is stamped on the shank just above that ferrule.
