Gun values and prices vary wildly in different places..
Where I live what a model 12 is valued or price at may be different than where you live.
What a gun is valued at ....What it is priced at and what it actually sells for can also be three different prices.
With that said...
Most decent Model 12's start around $500 where I live depending on shape , features and choke.
Generally the better the shape and the more open choke the higher the price.
A full choke gun being less desirable with the need for steel shot in many areas....
I would not do the trench gun mock up with most of the Model 12's that I have seen lately.....they are in too nice of shape.
Speaking for myself , I would only do this with a model 12 that was beat or had a bad bore near the area of the barrel that would be shortened.

I picked up a Winchester '97 take down that had a dent near the muzzle, so I cut it down and bought a heat shield.
The hardest part was filing the three screw slots that clamp the heat shield to the barrel.
Original model '97 trench gun barrels are marked "Cylinder" and are thicker walled, so when you use the correct round file to make the half round slot, the screw threads should tap the barrel as they cross over to the threaded side of the clamp.
I passed up buying a heat shield from Numrich because they're made out of thinner materials then the company listed below.

Maybe get in on this one?

WW11 Riot Shotgun - Winchester model 12
Same as the trench gun, but this batch was given to the Navy/Airforce to guard vehicles/ Receiver and barrel date To 1943. Original parkerization in decent shape. Totally functional. US markings with flaming bomb insignia on both the receiver and barrel are sharp. The “full” marking is crossed...

Thank you for the input. The one I am looking at was about $450. Shape... well... it looked pretty rough to be honest, If its still there, I'll inspect more, and maybe make an offer. I don't think it had a choke. I would only get it, if its a good deal.
I'm asking mainly because I don't want to ruin a "super collectible" but it appears that they are fairly common guns from what I read. And it definitely wasn't a serial "1" lol

Got an Early Christmas present 
. The barrel was longer (30" and now is 20 1/2) and I am working on the trenchgun project now. Its a 1951 in very good condition. It only had 1 flaw on the mag tube that looked like someone cut a tiny slot to get a screwdriver in to pull a dent out or something. Nothing that I cant fix.

So, I'm running into an odd "problem" here. I had measured my barrel by putting a stick in it and marking it. End of muzzle to breechface was exactly 30". I then Cut it so it is 20 1/2". Now I have gotten my heatshield with bayonet lug and the barrel is 1/2" too short!? What in the world happened there??? Do I leave it like that or do I weld 1/2" piece of barrel back on? This is mainly a cosmetic issue. Any compensators or anything that could fit in there and be clamped?

Actually since this is a takedown model, maybe the mag tube is longer? I see in other pictures that the heatshield ends flush with the back of the foreend. Mind is 1/2" more forward.
EDIT: I see the issue. 5 shots vs 6 capacity. I think I could modify the Tube to make it fit perfect and still have 6 shots while retaining the takedown option...

There is a guy who makes a special ammo follower and spring that allows you to load 6 rds of modern ammo, as in the old days shotgun shells were an 1/8" shorter.

model 12s in good condition are getting tougher to find. Generally they got used, a bunch. Finding one that headspaces and is timed correctly should be first priority. By timed I mean it will not fire out of battery, a crucial safety issue, if the bolt is not completely locked in place it could damage you, the gun, or more likely both.
next is cosmetics, these were affordable field guns and some suffered from abuse and neglect. I have found that some hand work with abrasive papers to remove shallow pits and corrosion, followed by abrasive blasting and a zinc phosphate coating ( Parkerizing) makes for a nice military looking gun.
If you really have to have a heat shield, install it before cutting the barrel, and have it parkerized along with the rest of the gun.
Furniture is widely available and shouldnt be a problem, just be sure the stock mates nicely with no gaps at the receiver.
Texas armament is an excellent place to send it out for parkerizing

The screws that came with this were apperantly made out of butter. Replaced them with some 10-32 Allen Head. Not periodic correct but more durable. Next question is, where do I find a replica of the M1917... Or would an M1 or 1905 bayonett fit too?

WWI -Vietnam era trench guns were fitted for the 1917 pattern bayonet.

Here's a disclaimer from a company that makes reproduction heat shields.
IMPORTANT: This bayonet attachment will fit only the Model 12 commercial barrel. If you have a Model 12 original trench gun you need to order a Model 97 bayonet attachment. The original Model 12 trench gun barrel is the same diameter as the Model 97. The commercial barrel is smaller in diameter and that is why we came out with this model. Be sure that your gun is a standard model 12 commercial chambered for 2 3/4 inc shells. Some special models ( Heavy Duck) are chambered for 3 inch shells and have a slightly larger barrel diameter. Our attachment will not fit these models. Also if your barrel is marked: model 1912 the attachment will not fit (too tight). The attachment will fit only standard commercial model 12 barrels marked: model 12

I had to file a tiny bit and the screws left a thread imprint. I'm not too worried, I'll come up with something to make it tight. Maybe putting a shim around the top part of the barrel or.... filing the slot wider so it clamps tighter.
I did not buy the $200 version, I think thats outrageously expensive!
