I bought a nickel plated M19 snub that had a cracked frame right under the forcing cone, weld repaired. The nickel plating was not factory original and an attempt to disguise the weld.

I sent pics to a Canadian S&W warranty shop who congratulated me on my "paper weight". Apparently it happens on steel framed guns not infrequently when barrels are removed.

I got my money back, the seller feigning ignorance.
