Yes, but darn few.
Up until last week I knew of none that would fall into the 1980 to the present catagory, only that they made a very few 1st and 2nd model N frames in .38-40 WCF. Last week someone posted that they found in a pawn shop and bought a 5" full lug pre-dash 610 in .38-40. That just goes to show that you can't say S&W didn't make something, at least not with confidence. I still have my eye out for that .38-40 tripple lock registered magnum, but don't hold your breath waiting for me to post pictures. For better info on 1st, 2nd and possibly 3rd model N frame .38-40s try starting a thread in the 1896-1960 catagory.
Best Regards,
