I haven't seen thw action first hand, but client says it's stamped 1924 Turk and has square threads

Anyone know about this configuration?

Wait for it! Wait for it! dpcd will arrive soon!

ahshit...disregr?'
;;'';ad. turns out he he was asking about a BARREL!

Have never come across a Mauser with square threads.

neither had I, until I pulled the barrel from my FN commercial… 10tpi 1.040” major. Apparently someone ordered a bunch from FN due to an excess of NOS 1903 barrels. A bit like the PH Midland story I guess?

A "Bannerman Special" ?

The "1903 thread" FN's are definitely not common in Oz, but they are out there. I've got one, and have seen several others. In factory form with a barrel still installed, they are pretty easy to spot once you know how.

I submit that there are None of these in the US; I welcome any sightings of one.
And of course, any 03 barrel would have to be modified to work; cone breech and all, not for a Mauser.

that thread I linked to suggests there are some in the US. Unless of course they’re all lying

how’s that?

Yes, the elusive "Mausingfield". Looks like they machined off the coned breech back to the chamber mouth. Then removed the fifth thread and made a clearance cut to get the proper shank length. If carefully done, they may not have even needed to use a chamber reamer. It also appears they machined a flat on the receiver shoulder as a secondary torque shoulder. Clever boys. If they left the "flaming bomb"on the barrel that would be a tip- off.

Your link suggested that Herters was the one who imported them; they have to be super rare since NO documentation/books even mentions them. ZiR has one, and the OP has one. I was buying Herters barreled actions in the 1960s and they were all V.
Is FN the actual maker of them?

My guess is that FN made the actions, but the square thread modification was "aftermarket".

You can't re thread a 1.1 OD V thread with a smaller, 1.040 thread of any form.

FN made the actions I have seen with the 1903-form barrel threads.

FN clearly marked their makers name on each in their normal way for that time.

I'm cutting and processing gun blanks at the moment, and have no opportunity to check my action. Details from memory below; I'm pretty sure they are correct and sure hope they are:

Double-broached, with solid LHS receiver wall. D&T from the factory, no charger guide. Typical FN bolt handle job of the day. Commercial sporting rifle action, not military. Also from memory, they are marked on the LHS front ring under the wood line LOT-XVI. Of the handful of square-thread FN actions I have seen, every one had the LOT-XVI marking. Some actions may have had this scrubbed by now.

Perhaps FN made other actions not marked like this. Perhaps they made other batches (LOT-???).
There would probably be more info on them somewhere on the net.

I years ago rebarreled one of these square thread FN actions, first one I had ever seen

My Father remembered that Firearms International imported many of these FN actions years ago

Last year I picked up a as new never barreled action of this variation.
Normal FN marking on the left side wall, and normal proof marks on the left front ring below stock line.

Two odd things is

A. a large ST stamped on the bottom flat of the receiver behind the recoil lug
B. No serial number on the receiver, which means it was brought into the USA before 1959

It is also a Deluxe action as its cut for the side safety that would lock the bolt when the safety is on.

I know of another Old Gunsmith in Oregon who has handled 2 of these actions as well

Just another ODD thing about Mausers

Jim Wisner

If they were not barreled actions then the barrels were threaded/chambered to fit the actions . Correct ?

spot on


So, apart from square threads being slightly more laborious to cut - is there any inherent disadvantage in building an accurate hunting rifle from one of these?

And why the square cut instead of the standard/common v cut threads? And why were they made in the first place?

the story goes there was a big load of NOS 1903 barrels. Yes they need head spacing/cone removing(?) but I there’s still slightly less work than starting from scratch. I guess it made financial sense back in the day when labour rates and material costs were different.

After WW2 and way into the 1980s, Springfield barrels were very common and sold for less than ten bucks apiece; I bought a case of them in the Army Depot wood box for $15 each in about 1990.
Other than one special order, there was no reason to make them like this.
However, these actions are completely undocumented in any book I have; why did not Kuhnhausen, or De Haas, Olsen, and others, write about these?
Because they only made 8 of them. More seem to be Down under than here.
Yes, the cone definitely has to be removed.

Funny thing; in my lonely little shop I have come across one of these and rebarreled it for a client. It was definitely a square threaded action of Mauser design. Does this make me famous?

So, do you think these were threaded by FN, or did they supply unthreaded receivers to the manufacturer where they were threaded and fitted with the Springfield barrels? As to why they were built, I agree there had to be an opportunity someone at the time saw to make a profit. If you can get nice barrels for a few bucks, why not fit them to a FN Mauser action? Apparently, it didn't work out and the rest is history.

Yes even seeing one of these super rare artifacts does make you famous, but then again, you are already famous to me.
I would opine that FN did the threading at the factory. Why? Springfield barrel threads are all timed; not that we need that on a Master (no extractor groove), but the front sight base has to be pointing toward the sky. OTOH, the surplus barrels would be custom fitted anyway....
And most gunsmiths back then could not thread a receiver. Now of course, all of them can. (This is to avoid all the hate mail I get from gunsmiths)
