The father in-law asked me to take a look at it because it wasn't ejecting the shells but I think I got it working now but I would like to be able to tell him the year of MFG the serial # on the receiver and the barrel both say 158725. The other thing is I read someplace that these came with either a 3 or 5 shell mag tubes but this one will only take four in the tube no matter how hard I try, could this be a mag off a A5?

Finding or figuring out Remington dates of manufacture can sometimes be rough on older guns. This is the best info I have but it doesn't have anything prior to 1930. Hope it helps you out.

Edited to add: I never used the Browning or Remington auto very much. Most of my personal shotguns are all Winchester 97's. So I don't know the answer to your question about the magazine tube.



Remington Year of Manufacture Codes maybe found on the barrel of your Remington rifle [or shotgun] on the left side, just forward of the receiver; the first letter of the Code is the month of manufacture, followed by one or two letters which are the year of manufacture. For shotguns with removeable barrels, the code will be valid for the manufacture of the barrel; maybe for the receiver, as barrels do get switched around.

Month Codes: [first letter]
B - L - A - C - K - P - O - W - D - E - R - X
1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - 11 - 12

* the years 1943 though 1953 had double letters: ie, MM = 1943

As maybe seen, the year code letters duplicate; some knowledge of when the model was introduced should resolve the actual year of manufacture.

Wow, thanks for the reply but still not sure that helps because as you can see in the pic there are lots of letters and #'s on the "bottom" of the barrel, it looks like (from left to right and inverting the upside down letters) E mt D? 131 x. Or maybe I'm just not reading the code right.

Sorry I can't be more help to you. I am not sure how to read those markings. It looks like your barrel has a S/N that matches the receiver, correct?

I am pretty sure Remington manufactured the model 11 between 1905 and 1948. I don't think the early ones were even marked model 11. I think they started that in 1911. If my bifocals and magnifying glass are correct your barrel is marked Remington Union metallic Cart Co. I know that was an old name for Remington arms back in the teens and early 20's. That's about all the info I know.

Edited to add: I did some searching on the net and it appears that Remington didn't call it the model 11 until 1911. I also found where someone posted that Remington changed the name from the Remington Arms Union metallic Cartridge Co to Remington Arms Co Inc in 1920. So if the person that posted that is correct it would appear your gun was made between 1911 and 1920. That is if the barrel S/N matches the Receiver. I assume your gun is marked Model 11.

Again sorry I couldn't be of more help. Let's hope someone on here is a Remington collector and can narrow it down more for you.

Just got off the phone with Remington, the guy in the "historic firearms department" says it was made in 1914. But thanks Mac4570 for the info you posted, it will be nice to give the gun back to my father in-law with a little history to go with it, he likes that stuff.

The barrel and receiver do have matching serial #'s and it is not marked Model 11 anyplace on the gun, I took pic of all the markings and put them in the post above except for a small UMC trademark to the rear of the trigger guard

Hey that's great news and I enjoyed learning something about Remington shotguns today.
