I found some more info on the Ithaca Model 37 riot/trench guns on. Still yet, if a guy wanted to add on an eight-shot magazine could he not SELL his existing barrel and BUY a barrel that better suits him? Never made it over to the equipment exchange, huh? How much is a new magazine tube and spring, $30? I don't want to hear about your latest garage sale exploits either. At any rate, you are not going to find a Model 37 Ithaca in good shape, with good wood, and a barrel that hasn't been messed with for your unrealistic price on a regular basis. Applying your cockeyed logic, Ford pickups are $50 vehicles.
Granted it had no engine or transmission, but I gave $50 for a full size Ford pickup. Using your twisted analogy, I once bought a Ford pickup for $50. Okay fantasy man, I'm not talking about some worn out, tired police trade-in with the barrel bobbed back. Tell ya what, would you buy every Ithaca 37 I can get my hands on for, say, $250? Since you buy and sell 37s all the time, for apparently a lot more than that, you should be all over such a deal. Just stay right where you are, several states away from me. Maybe you better leave OK and move to AZ. I personally bought an Ithaca 37 with a bunch of ammo about five years ago for $150 and sold the gun about a year later for $180. If you want to see a sub-$200 Ithaca 37, you might try Pawn World right here in my dinky little AZ town. Jim are you still rambling on? Had a hard day, buddy?
The wheels there decided that they ought to get into the repeater business and there was this Pedersen/Browning design that Remington was no longer using and the rest is history.
Ithaca was known prior to the Model 37 as a maker of high grade custom doubles, but due to the depression, was sinking fast. These were all discarded for Remington's own in-house design, the Model 31. A twenty gauge version debuted as the Model 1917 Remington and both the Models 19 were superseded by the Model 29 Remington (which is actually closer in design and manufacture to the Model 37 than any of the earlier incarnations). This first appeared as the Remington Model 1908 from Irwin Pedersen and evolved into the improved Model 1910 from John Browning. It is not entirely a John Browning design. Most items should be available from Ithaca, too. However, there were most certainly eight-shot Model 37s and it is certainly possible to modify yours.Ä«rownell's used to sell extended magazine tubes and Pennsylvania Gun Parts 1701 Mud Run Road York Springs, PA 17372 (717) 259-8010 had everything else. The second option here is to remove the magazine stop and have it silver soldered as needed. A few of these barrels are still out there, but you'll have to look. For a time Ithaca offered the Model 37 DSPS with an eight-shot magazine and a barrel with the magazine stop extended further towards the muzzle to accomodate the longer magazine tube.
So if you can't extend the mag, cut the barrel like rigidrotor. Not sure, but I don't think you can get an extension mag for an Ithaca 37 because the mag is integral to the action.
