My WW2 Trench Gun

Sun, 16 Feb 2025 23:49:23 +0000

Wish this baby could talk! Just a hunch on my part, but would not be surprised it was in Vietnam. The overall condition, patina and pitting, indicates to me it has seen some action. I forgot to include the bayonet I have for it. I just oiled it up, hence the shine on the stock.

Over the weekend I saw an exceptional display of WWI and WWII US shotguns at the OGCA show. Unfortunately I was unable to take any photos. Hopefully photos will be available on the OGCA website, if so I will post a link.

Price WAY too good to be true

Only one picture with no details

Only one listing for this seller

Only a vague location of somewhere in OH

The picture and text are from the website "hlvfineguns" which is in AZ and lists this gun for $9500

Scammer too stupid to put up a credible scam.

EDIT:

Listing already flagged by site admin.

He had listed it for $1200!

here's the original listing that the scammer pirated

Ithaca 37 for sale on Web...

I have just begun my fore into combat shotguns, thanks in no part to Sandman. Always looking, and learning about the different models throughout their evolution. But, I have to admit, if I bought this one my wife's head would explode...I barely survived the Thompson I pried away from Sandman.

US Marked Model 12

Wed, 08 Jul 2020 13:51:03 +0000

Im in the market for a US military Model 12 and have a question. There are the obvious "trench guns" with the bayonet adaptors fastened to the barrel. There are also other model 12's that are US marked on the receiver along with the military acceptance stamps on the stock etc. What is the difference between these models and what were they used for?? There is a dramatic difference in price between a trench gun and the Model 12 with just US markings.

thx

Were the riot barrels marked with the serial number like the trench guns or not?

I'm looking at one that seems correct but has no barrel serial number

Opinions on Ithaca 37 US marked

Fri, 21 May 2021 18:22:07 +0000

Organizing the safe and pulled this one from the back. Had for 8-10 years, 989xxx serial number. Parkerized with 20 cyl marked barrel and never drilled for front sight, under barrel is not recessed for a heat shield. No sling swivels and plastic buttplate. Interested to hear what people think about it and if its a real deal military gun.

Stevens/ Riverside 520A build.

Fri, 07 May 2021 16:28:30 +0000

Now that my M12 is done I can get started again on a Stevens/Riverside 520A that I bought in 2019. Planning on leaving the original 30 inch bbl alone but building a second trenchgun bbl assembly. Another of JMB’s brilliant creations. I’ve since found an ‘in the white’ heat shield, bbl, mag tube plus action bar, lower swivel and a plain stock and pump handle from GPC. Started bluing things yesterday. Coming along.

Update—started fitting the too proud stock to the tangs and recvr today.

New to the M12

Thu, 31 Dec 2020 04:55:53 +0000

Hey guys, I recently had someone offer to trade me his Winchester M12 plus $500 cash for one of my ARs, and I just came here for knowledge on the subject of the M12 as Ive never really been into it. He says the gun was produced in 1941, has no ordnance markings, and was a M12 he made look like a trench gun by adding the heat shield and a 1917 GI bayonet. Regardless, I think adding a slam fire to the collection will be neat, but I just was wondering if anyone could help me figure out what Im getting myself into. The stock set seems to be in pretty rough shape with a coupe cracks

Thanks in advance

Shotshell lengths and mag capacity

Wed, 03 Mar 2021 01:14:41 +0000

Not particularly germane to US martial shotguns but...

It seems that not all shotshells are created equal. I just picked up some NobelsportItalia 12 ga. buckshot rounds. I already had several other brands in my stash. All are nominally 2-3/4”/70mm which is the chamber length necessary to accommodate the fired hull, not the length of an unfired round

The unfired PMCs are the shortest at 2.22” AOL

The Remingtons are 2.30” as are some Kent birdshot loads.

The Winchesters are only slightly longer at 2.31

The Nobels are a whopping 2.48”

All the brands other than Nobel use the familiar star crimp; the Nobels use a plastic “card” over the shot charge and a short roll crimp. It appears that the fired hulls will be very close to the same length as the other brands.

None of this means much until I load my 11-87P. It has an 18-1/2” barrel with a barrel length mag tube. The tube will hold 7 of the PMCs but just misses being able to take a 7th Remington or Winchester. With the Nobels the limit is also 6 but with very little unused tube length.

So if you have a shotgun that comes close to accepting one more round, it may be worth looking at some off brands to see if they are sufficiently enough shorter fit in that extra

Price for Average Condition Ithaca 37 Trench?

Sun, 21 Mar 2021 03:17:03 +0000

I am new to US Combat shotgun collecting, but leaning towards Ithaca 37 Trench. If I can find a real one, what king of price should I expect for a well used but working condition Ithaca? Vietnam era production would be okay as long as it is a U.S. military model.

I am looking at an Ithaca 37 that had the barrel shortened to 20 inches with a reproduction barrel/bayonet shroud installed and reparked and they want around 1500 dollars for this faux model.

Thank you.

520/620 Trench Barrel on GB

Has proof and flaming bomb markings with 3 grooves near muzzle to attach the heat shield

WW1 1897 trench gun on GB

Wed, 18 Nov 2020 12:29:04 +0000

According to Bruce's book this gun is well outside the WW1 sn range but the seller provides a piece of paper with a sn range that exactly matches the gun for sale. Its a great looking piece but idk about that 1920 serial number...hmmm

Opinions on possible Winchester M12 Trench 'Front Half'

Tue, 13 Oct 2020 16:01:57 +0000

Hello, scrolling past this forum and seeing all the talk on real vs fake military trench guns reminded me of an old part I've had for 8-10 years now. It's the business end of what I hope is a model 12 trench gun, without a heat shield. Serial number 1020177. I bought a mixed up model 12 on gb kind of on a whim because it was so cheap, I sold of the receiver section but kept the barrel end. It's grooved for the heat shield screws, if I remember correctly its marked CYL, don't recall if there are other military markings. It's in deep storage back at my Dad's house, I just have these phone pictures I took a couple years ago. It's always been a 'maybe I'll do something with this one day' thing.

Rambling aside I've only got a couple pictures right now but I'm interested in hearing any opinions on its authenticity and value.
