Old topic but yeah they did. I have an early(ish) 60 I bought new in 1982 or so (no dash anything ABH9XXX) and wanted to bob it maybe 2 years ago or so. I called S & W and asked for a replacement before I bobbed so I'd have one. They said don't bob the original as I would have difficulty finding another. They did have a bobbed one in stock and sold it to me for about $35. It dropped in without issue. It did make it DAO. I tried calling S & W today about another part and never could even get through to talk to anyone.
