Mystery Barrel ID #1, or Barrel thread trivia!!

ahankster
I posted a question earlier about reference sources for barrel threads. Really appreciate all those that tried to assist, but there really isn't a place to go to match up unknown barrels to their respective receivers. This one should be pretty easy, I am pretty sure as to what it fits. But, wanted to check with the experts to make sure. This barrel is stainless and marked 7.62x39 and really has no other markings. The pictures are below;




The threads appear to be 12 per inch. As the pictures indicate, the outer diameter of the threaded area is 1.092 in, the inner dia appears to be approx 1.021 in. The diameter of the barrel after the threads at the breach is 1.118 in. This thread pattern, shape and number appears to be exactly like another barrel we have, a 03 A3 barrel, leading me to believe it belongs to the Remington family.
Any help in this area is greatly appreciated.
We have two more to follow? Should be interresting.
Thanks again.
Hank

    Nope, ahankster-- those threads and dimensions are typical for a large ring Mauser. Large rings have a major diameter of 1.100 inches, 12 theads per inch, shank length approx .625 inches which looks like what you have. Typical small ring Mausers, '98 type such as the 33/40 have a major diameter of .980 inches, 12 TPI, .625 inches shank length. Other small rings like the '93 Mausers have a major thread diameter of .980 inches, 12 TPI, .645 inch shank length. As you've probably seen in this forum, the Turkish Mausers may have different dimensions. The 1903 & 1903A3's use square threads, 10TPI, which are very different from the barrel you picture.
    Cheers, OleDuk

    Threads can be measured using a "three wire" method found in "Machinery's Handbook". Any good gunsmith or local machine shop should be able to identify your thread both pin (barrel) and box (receiver).

    OleDuk and dHeffley,
    Thanks for your information. I came by a bunch of barrels, sold as a lot, in a local auction and just couldn't pass them up, too good a deal. Most are either new, never installed and in perfect shape, some are never installed but need refinishing and some are old military barrels.

    The reason I thought this barrel was from the same family as the 1903 A3 is that I have one that has the RA, flaming bomb and 7-44 on the end, pictured here (which I was almost certain was from the 03 A3), and the threads on this one aren't square and are almost an exact match for the stainless one, there is about .010 difference in major diameter.




    Thanks for the info, am I wrong about the markings on the barrel we thought was from the Springfield?
    Thanks
    Hank

    oleduke is correct about the first barrel, the second one is a 03a3 barrelm cut off and rethreaded for a m-98 mauser, i had a batch of m-1912 chilean mausers with these barrels on them.

    Man, I should have never doubted you guys. Definietly the "experts".
    OleDuk, I apologize for doubting you and am humbled by your knowledge. :)
    Showed the barrel to a local smith today and he totally agrees with you. As far as the O3 A3 Barrel, who would have thunk it, rebarreling an 03 A3 for a Mauser. Mike you are right on too, I am pretty sure. I knew the markings were from an 03 A3 barrel, but had never seen the barrel threads and never thought about it being rethreaded, it is in such good shape, still parkerized, I didn't think that would have been the case.

    Thanks to all you guys for the info. You are a great source of information.

    Absolutely no apologies necessary, Hank. The RA 44 marked barrel was made by Remington Arms in 1944. You used to be able to buy those barrels from the DCM for next to nothing,($2.00?), so a lot of folks would buy them and do all sorts of things with them. The last few of them that I bought cost me about $8.00 each, from a private source. One is sitting in an Arisaka as a .308W, another is in an old Mauser M93 as a .300 Savage. Another one wound up in, surprise, a Springfield. None of them has been fired. Those barrels were plentiful enough and cheap enough to just do anything with them and have a lot of fun. Not that way anymore. Too much(?) collector and restorer interest has run the price up to where, if you've got a re-barrelling project, you're better off with a commercial barrel. The commercial barrel is better, too, I'd say. Just keep asking questions. If I can share the little bit of knowledge that I have in this hobby, I'll enjoy doing it.
    Sincerely, OleDuk
