I have always felt that the important thing with a Model 37 (or ANY shotgun) is to get one WITH A RIB. I wouldn't want one without a rib. I would also think that full choke would be the most common. I have a model 37 that (I believe was made around 1953). Solid Rib- 20 gauge- full choke. It was the first shotgun I ever bought when I was about 16 years old. I had it reblued and I will never let it go. There is one for sale right now that I was just looking at on American Trapshooter.com with a spare rib and probably some on Guns International. But I don't think that any Ithaca Model 37 is THAT big of a deal or rarity in any configuration- money-wise. Good luck.
Well, I hate to disagree with you, but I’m going to. I don’t think a rib is essential on any shotgun. I’ve shot limits of chukars, huns, grouse, pheasants, ducks, etc using Winchester Model 12’s & 97’s , Browning A5’s, Ithaca 37’s, Remmy 1100’s, etc.
I just took a 16 gauge Winny model 12 to Nevada for a 3 day long hike in the mountains for Chukars….26” ribless barrel. Chukars never knew I was shooting a ribless gun.
I never once felt my shooting would improve with the addition of a rib. Truth is, I don’t look at the rib or the bead when I shoot birds or clays. I shoot my solid rib Model 12’s just as good as the ribless ones
Anyways, I’d still like to know if Ithaca made model 37’s with 26” modified or full chokes barrels. If anyone comes across an example, even if it’s just for reference, I’d like to know about it.
