As WWII began, the Romanian Army used primarily Mauser rifles and ZB-30 light machine guns, along with a wide variety of different submachine guns. It was decided that a domestic SMG design was necessary, and by 1941 a gun had been designed at the state arsenal at Cugir (the same arsenal that produced the thousands of Romanian AK rifles was saw imported into the US in past years) by Nicolae Sterca and Leopold Jaska. The gun was named the Model 1941 Orita, after Captain Orita, another engineer who worked on the project.

Although the Orita has the look of a stamped second-generation SMG like the MP41, it was actually much more like the precisely machined first generation of subguns. The receiver is a milled piece, and the gun is a sturdy and durable piece of kit.

Mechanics

The Orita fires from an open bolt, but it is a bit more complex in design than the typical open bolt gun. Instead of having a fixed firing pin, it uses a floating pin and lever system to fire. A projection on the front of the bolt slides backwards when it hits the barrel face, which forces a lever inside the bolt to rotate around a pivot point and strike the firing pin, which then hits the cartridge primer. This system is certainly more complex to manufacture than a simple fixed firing pin, but it prevents the possibility of an out of battery detonation. It is relevant to note, however, that this will not prevent accidental discharge as is possible with many open-bolt guns. If the bolt is closed over a loaded magazine and the stock struck against the ground, it is possible for the bolt the bounce back far enough to pick up a round form the magazine, which it will proceed to chamber and immediately fire.

Beyond this, the mechanics of the Orita are pretty standard. It used a non-reciprocating charging handle on the left side of the gun. The magazine was a double stack, single feed type that held 32 rounds and was pretty similar in appearance (though not interchangeable with) to the MP40/41 magazines that were also in use by Romanian forces. The Orita mags can be distinguished by the deep guide grooves in both sides, which extend all the way up to the feed lips. The single-feed aspect meant that the mags were difficult to load by hand, and an interesting rotary loading tool was designed to go along with them.

Variations

The first production version of the Orita had a number of relatively expensive features characteristic of early SMGs. The rear sight was a tangent type graduated from 100m out to 500m, and it had a crossbolt-type safety and a semi/full fire selector above the trigger. After the end of WWII the design was simplified, and fire selector was removed, making the trigger mechanism full auto only (with single shots to be made by trigger control on the part of the shooter). In addition, the manual safety was replaced by a grip safety on the underside of the wrist of the stock, and the rear sight was replaced by a simple two-position notch.

There were clearly some iterations between these two standards as well, as some photos show a grip safety and normal foreend (as below), while others show a metal wrist built into the receiver and wood panels added to the sides for a gripping surface (as in the two late model guns in the top photo). This might be explained by a combination of converted early guns and later guns built from scratch as second variants.

There are many brief references to a folding-stock version, but I have been unable to find any photos or firsthand evidence of these. If they were made, it would have been is quite small numbers.

Usage

Ultimately, domestic production of the Orita could not keep up with the demand for submachine guns by the military, and Romania continued to use a wide variety of captured and purchased guns from other countries, including the MP41, ZK383, PPSh-41, Beretta M38A, and others. I found one reference to a total production of 4000 Oritas, but have not been able to confirm this.

The guns, while expensive to make, were pretty good in the field. After WW2 they continued to be used by the military well into the 1950s, and as late as the 1970s by national guard units. Eventually they were all replaced by AK rifles.

  1. Hey Michael,

    If you want i can drop by at the local military museum in (Oradea) Romania and send some more pictures of the Orita. It has both models side by side for a good comparison. (as far as i can remember)

    Here’s a few photos of the folding stock version:
