I thought my Fox fetish would keep me preoccupied but I've found a 20ga Ithaca Flues (1 1/2) that is awfully tempting. I've heard about these lightweights having trouble with frame cracking but that it was limited to a certain production era/set of serial numbers. Unfortunately, I do not have the serial# of the gun I'm looking at. Are there any physical characteristics that would help identify production era? Is this really a concern with the appropriate loads?
The gun in question is just under 6lbs with 26" bbls. I've seen some as light as 5lbs 4ozs with 28" bbls. Thanks.
