I recently acquired a Winchester Low Wall. It's been rebarreled with a 25 1/2" heavy barrel and chambered for the 25-20 SS. DST's have been added and I installed a Fecker scope that looks right at home on the rifle.
Attached are some photos of the rifle and what markings I can find.
My guess is that it was barreled by "Doug" who may have done the rest of the work as well. No serial number, which was lost, when it acquired the DST's. 
I have the Campbell Winchester single shot reference books but not enough experience to easily answer my questions.
Does anyone recognize the markings or have any idea who Doug might be?
I wonder if "RW" might be the barrel maker?
How can you tell if a low wall action is original or a converted high wall?
Thanks for your help.

Hi Otto, the action looks like a Winder musket, probably a .22 short in it's first life. They were highwall actions Winchester had on hand and cut down to Lowall profile. The rifles were sold to Uncle Sam for trainers during WWI. You can see the dead give away in the photo of your upper tang in the "flaming bomb" stamp. 
If the "DOUG" is Douglas barrels (which I'm sure Frank is right about) then I would guess the rifle was done post WWII. So "RW" may still be around. I would guess the 25/20 SS chambering pointing to with the last 30-40 years as it was dead as a hammer before that.

That's a good guess, Bob!

If you go on the ISSA site, you may be able to find contact info for Pat Weber, his wife. She might be able to help, at least in IDing the mark as how Russ marked his work.

chipmaker,

I think you've got a 3rd Model Winder Musket action that would have been made in the early 20's. During WWI, it became obvious that many soldiers had little or no experience with rifle shooting, and therefore, the military looked for training rifles to teach Americans to shoot. Yes, you should have bought the Russ Weber breech seater that came with the rifle! 

Russ Weber built two rifles for me.  I pulled the forends off and neither of them is marked "RW".

One gun was built around 2012 and the other 2015 or so.

Maybe Russ marked his barrels in his earlier years?

What does the muzzle and crown look like?

Thanks for the explanation of the three types of Winder muskets. Since your response , I've also found an article by Bret Hartman on Winder muskets that is an excellent review of the three types.
I agree that my rifle uses the type 3 action. It is drilled and tapped for the Lyman receiver sight but Hartman says that the Lyman M-53 sight was used, instead of the reversed M-41 shown in Campbell's book.
Does anyone know if all Winchester high wall actions were drilled and tapped for tang sights or was this an option?

Smoke
Thanks for taking the time to check your rifles muzzle and markings. I agree with Frank that many gunsmiths stick with a muzzle crown that works for them but Russ appears to have used different types.
It appears as if Russ Weber isn't likely to have been the maker of my rifle.
Thanks to all the responders.
Otto
