Found this 2 1/2” 19-3 on the auction site and it looks as if the s/n in the yoke has been scratched off. I know it may have been obliterated by photo shop or something, but in the ad, he says the s/n is K480xx, so he has to have left out a digit. But K480000 would make it a 19-2, wouldn’t it? And the 2 1/2” barrel didn’t come out until the end of the 19-2 production. Something just seems fishy!
