I'm starting a new research project so if you have one of these rifles please contact me. There has to be more of these out there. The Marines built 40 of these for Sniper Training around May 1941. Which 20 (each) went to the 1st and 2nd Marine Divisions.
Then the Marines built 80, forty each to the forming 1st and 2nd Raider Battalions in Febuary/March 1942.
As of right now, only 3 of these are known. One that is about 300 digits off this one in the 1.25 range. Then a third that is in the 1.33 serial range that was actually sold at CMP auction.
I think most people that know of this variation, think of the Mann Niender as a WWI rifle, but it really wasn't. There were a 150 built in May and June of 1917 by Niedner for the Marines, but he was then fired as being a potential German Saboteur. Winchester then received the contact for the A5 sniper rifles, but that was not a Mann Niedner style rifle. By the time the Marines started to produce their own version of the Mann Niedner in house at the Philly Depot, the war was basically over. So the Mann Niender's were used in training or by the Marine rifle teams in between the wars.
Some Mann Niedners were built with a heavy Remington or WRA barrel, sporter or commercial stock with lyman 48 sights, and were called Free High Pressure rifles. The Marines nicknamed these rifles as "Free Rifles"
Just reading the docs, I do believe this receiver was likely at one time built into a Free High Pressure rifle for the Marine rifle team. That is why I think it has the lyman 48 sight holes. The holes were drilled before it was parked the last time, so I do think they were drilled while in service.
At the start of WWII, almost all of the Mann Nienders left in the Marine Corps inventory had been broken down and show up as loose components in storage at the Philly Depot. It appears at the start of WWII, the Marines just removed the parts from storage and built sniper rifles out of them.
As for this particular receiver, I believe it was in a shipment of 50 1923 National Match Rifles that the Marines had kept in 1928. At least one from this shipment was built into a Free High Pressure rifle, which is still located at Quantico. I assume this one was as well.
The serial is 1257998. Serial on the bolt is faint, but is 1277332. Barrel is a 5/38 and has the same vise pattern as you see on the Unertl Special Target rifles. The Marines drilled the Hatcher hole, and put in a 2nd gas relief hole in the bolt. The bolt is a straight handle J5.
If you do have one of these rifles please contact me. I don't think a lot of research has been done on the WWII Mann Nienders yet. The Unertls have always overshadowed this rifle, and everyone always thinks of these rifles as only a WWI rifle.
But the WWII Mann's have a very interesting history. For sure 11 of these were used on the Canal and probably more that were not recorded. One was pictured in use on Bougainville. The 5th Marine Division received 20 in 1944 and the 5th Division participated in action on Iwo Jima.
These probably saw a lot more action than ever has been recorded as the entire war the Marines kept on confusing this rifle with the 8X Unertl Sniper. Everyone had a tendency in the Marines to just call them both the 1903 Sniper in logs and official reports. Which caused mass confusion for the HDQ Marine Corps.
These were also the main training rifles for the Marines that went to sniper school in 1943 and 1944.
Again if you have one of these please contact me, there has to be more of these out there.
