In all of the postings I've read here the M50s have numeric values only in the S/Ns.  Mine is S48XX.  What if anything does that number indicate about the origin/history of my gun?

Your M50 was made in 1957. This is the last known year of production. A total of 907 M50's were made in 1957 ( serial numbers S4700- S5607). Many of the S prefix serial number M50's were sold thru Numrich Arms when H&R went out of business. I suggest you buy Frank Iannamico's excellent book UNITED STATES SUBMACHINE GUNS for more info on the Reising submachine gun and other WW2-post war US SMG's. Todd in Oregon

In addition, Frank has a book dedicated to the Reising submachinegun and the semi automatic models.

Title of the book is: “The Reising Submachinegun Story.”

Not sure if it is still available.

Purchased it from Frank years ago at a Thompson collectors event...

The Numrich ‘S’ prefix numbers seem to be all military model repros built on commercial model numbered registered Reising receivers. I’ve brokered quite a few of these guns over the years and have yet to come across a commercial Reising with an ‘S’ prefix.
The Numrich military repros are very well done, in my experience, with all correct military parts and correctl6 parkerized. Buyers will pay a premium for these repros sometimes and at other times want a discount to a commercial value. FWIW

I have a S Prefix gun
Out of all the Reisings I have bought and sold 20+ now by rough count its been one of the nicer and better running ones I have ever had. Not to say the others didn't run well but I have NEVER had a problem with this gun and cleaning it hasn't ever been a priority.

Congrats on the purchase of your early manufacture M50 Loulittle! I'd love to see some pictures! Especially interested in the box. Is this your first Reising? Todd in Oregon

Just purchased a Reising M50 serial number 2031 . What if anything does that number indicate about the origin/history of my gun?
It also has a decal with San Patricio County 0675 on the stock.

As posted above the S prefix designates a 1957 manufacture date, post war production used letter prefixes.

There has been speculation that the S-prefix Reisings were all assembled from parts by the Numrich Corp. This MAY be true to some extent as they bought a lot of H&Rs inventory after the asset reduction sale of 1985. However, during research for my revised M14 book I found out a lot of info about the H&R demise, through court documents and newspaper articles. It has often been thought that there was a bankruptcy auction. Not true, they did file Chapter 11, and there was an asset reduction sale in 1985 approved by the court so the company could keep operating and pay employees. I obtained a ATF transfer form dated 1985, (they closed the doors in 1986) the form had 66 M16A1s, 29 M14s, T48s HK clones, and a number of S-PREFIX Reisings. The guns on that particular form went to one individual from the Philadelphia, PA area John (can't recall the last name) but he was a mysterious guy, I spoke with several people who knew him, and did business with him, BUT I could NOT get anyone to talk about him. He apparently had some connections with Colt as well as H&R, a lot of Colt parts came through him. I visited a gun shop near Philadelphia, that had some association with this guy, a few years ago and spoke with people who knew him BUT would not talk about him.  Last I heard he had dementia and passed away. If you knew this guy (Black River Bob?) I would love to hear from you.

Mine is 98717. Manufactured 1943. Runs good, but I've only had it out a couple times. 12 and 20 round mags work great.

H&R never used the nomenclature's commercial and military Reising models. Someone made that up to differentiate between the two. The Marines bought and fielded both variations.  

I found a lot of H&R and Marine material at the National Archives. A more accurate description would be first and second model (also never used by H&R).

The Marines bought a lot of the "first model" blued Reisings. Problems in the field resulted in it evolving into the "second model" around 1942-43. There are copies of many of the Marine documents in my Reising book that back this up.

 

1. Rust of the bluing evolved into Parkerizing 

2. Larger take-down screw that doesn't require a tool

3. Fewer fins on the barrel to make the barrel more rigid

4. Re-Design the selector lever to be used with muddy or wet hands

5. A second detent pin to secure the end cap

6. Re-design the trigger guard for more lateral strength 

7. Adjustable windage front sight 

8. Redesign the magazine catch

9. Eliminate the fixed hammer spring guide on the end cap (subject to breakage)

 

These Marine suggestions resulted in an "improved" second model Reising; an accurate description would have been Reising M50A1, but that didn't happen.

Based on your production dates and figures, is it safe to assume that 10529 was manufactured in January of 1942?
