Well it's been a while, so I'm going to step out on a limb and say it is doubtful that anyone can post an ad showing that S&W OK'ed .38-44 ammo in J frames, as previously posted. If I have read the 'book' correctly, J frames were not introduced until 1950, and that is the exact date of the K frame ad I posted above which did not list .38-44 as being OK in that bigger frame.
Let me know if I'm wrong, always looking for more S&W ads, thanks!
