Shawn,
* I believe Ron has hit the nail on the head. A DWM 1908 model made in 1911 for the Army.
* From the pictures, a very nice looking example. Have you identified the full S/N and suffix yet ("The full serial number will be found on the front of the frame and the bottom of the barrel.")?? I'd hazard a guess you'll find a small, lower case "c" or "d" suffix underneath the S/N digits of this example. The suffix is considered a legal part of the S/N.
* Properly marked in the commercial
style, you will find the last two digits(23) on the underside of most small parts including inside the grips. Also, a few parts inside (trigger, holdopen if present, receiver lug, firing pin) will bear the same last two numbers.
* Any marking on the holster? Could be on the back between the belt loops, on the front along the edge near the pull-up strap knot, on the inside of the bucket top, etc. If you find some, please post & we'll try to ID the maker and year of holster production. Could be die impression stamped marks or ink/rubber stamped markings(usually inside).
* You have what appears to be a nice, collectable grade, WW1 Army Luger. Trust you can appreciate the fine care given to this example over the 93 years of its existence.
Respectfully,
Bob
PS: Ron, you are one quick draw post ahead pardner!! Hope the repetition wasn't too redundant.
