Thanks guys... I'll look closer for anything that identifies the source of the bbls and report back if I find something. The weigth stamps are clear #3's. No damage of any kind to bbls so sounds like more metal is a good thing! Will be interesting to see how she patterns.

I love these Sterlingworth's... Have a later Philly SW (1929 mfg) and these barrels fit that gun perfectly and vice-versa. No such luck on earlier (1914) Sterly with 26" bbls. Have to see if they will fit to A grades as well.
