I've seen 12s and 42s with them. Uncommon to rare. The most intriguing M-42 versions don't have a factory Cutts at all. These are a select group of 2nd type VR guns, 28", with a WS-1 hand-stamp.
Am aware of about 4 of them. All round post VR, all SN 143k-146k. May be a few more. They derive from non-stamped barrels originally intended for Cutts guns later disposed of as VR skeet guns. They are the only credible factory built exceptions to the choke stamp nomenclature (skeet - .40 vs WS-1 - 12, 16, 20) I'm aware of.
