My gun guy also said that he has exchanged barrels on earlier Ithaca 37s without issue multiple times.He says that pre-855,000 guns are interchangeable with other pre-855,000 guns based on how old your barrel and shotgun are, but I have heard this is false from a variety of forum members and old timers at the gun club.
Is there any truth in what he says or has he been miss-informed Thanks, Flax. ![]() That translates into shipping both ways, 75.00 that Les says he charges, I do not know the local rate here by me. Is there any truth in what he says or has he been miss-informed He is smoking crack. The older barrel threads (pre-855,000) had a pitch to the threads, just like on a bolt. There is a dimensional relationship between the barrel face, the shoulder at the end of the threads, the face of the receiver and an internal shoulder. Where Is On Ithaca 37 Shotgun For Sale Serial Nbr OnThere will be a serial nbr on the front face of the receiver, running vertically next to where the barrel goes in, and the serial nbr on the barrel that also has a - (dash nbr) to indicate choke. Windows xp mini isoIthaca choke marking system: 1 for Improved Cylinder; 2 for Modified; 3 for Improved Modified and 4 for Full choke. There were also Skt marked barrels (or maybe nbr 5) In order to fit the barrels (from what I can tell by observation and talking to other folks) the barrels were screwed into the receivers and a witness mark put on them. If you look at the older barrels most if not all will have the witness mark. The witness mark allowed them to align the barrel in fixtures to cut the thread interrupts, the extractor cuts and to put the barrel lug on. You can fudge them by backing them out a little but then they wont headspace correctly. If they do start, they will usually stop before going into position. Because the threads have a pitch to them, the barrel is actually pulled into the receiver a small amount, just like a bolt is pulled into a nutthreaded hole when turned. A 14 turn does not translate into much movement, but it is there and has to be taken into account. To fit a barrel, the barrel face and the shoulder have to be carefully machined on a lathe a little at a time until the barrel will go into the receiver, start into the threads and then when turned, bottom out with the all the aforementioned features in alignment. A person has to understand the dimensional relationship before hacking away at the metal. ![]() ![]() The post 855,000 barrels simply use parallel V grooves, which allows barrels to be swapped back and forth. Sometimes due to pre-CNC machining practicestolerances, even those might need a little adjustment. After I see how this barrel works out Ill give Gerald a call and see what he charges.
