Correct, with the E.E.C. (Edmund E. Chapman, inspector between Aug. 1918 and June 1919) stamp and the serial number being 19615, it's a 1919 Remington-UMC receiver. With the slide, hammer, slide stop, stocks and probably the barrel having been replaced during it's rebuild. You have a nice keepsake there.
I have carried it everyday for over 18 months 
After having to sell my Kimbers, Colt, Taurus and Charles Daly I have finally been able to trade around for another 1911: Its a Desert Eagle G, a 70 series 5" government model. Going to shoot it today and so far I love its looks, fit and finish.
Let us know how it shoots 
I have heard nothing but good thing about the Desert Eagle 1911's

The new DETONICS MTX model, its the successor to the CombatMaster. This is the 1st production gun from the factory. I'm not shooting this one. It will live comfortably in my sare, unfired.
Not traditional looking but the function is pure 1911.
Its actually a 2 tone black over dark grey but looks all black in the photo
I will be shooting the prototype gun, which is nearly identical to this gun and is pictured in other threads here on INGO, the prototype has a titanium colored frame with a black slide. I figure that gun has probably 20,000 rounds through it already so its not like me shooting it will lower the value, but the 1st production gun, that will become a safe queen.
This gun uses many of the patents developed for the original Detonics CombatMaster, as well as many new ones. Its the first fully modular/CNC machined production 1911 pistol (as opposed to custom shop guns). The grip/frame is alloy, the grip comes off and can be swapped with higher capacity grips, but this compact variant holds 12 rounds of 45acp. The grip shape and angle are a bit steeper than a traditional 1911 and more like the BROWNING HP or CZ 75 grip shapes and the angle directs more of the recoil down the arm by aligning the bore axis with your arm, rather than high above it so the muzzle flip is naturally reduced.
The grip, being CNC machined inside and out, allows for tighter tolerances and that translates into a grip circumference that is smaller than many double stand 9mm pistols. The length of pull from backstrap to the front of the trigger is also shorter, making this gun easier to use by people with even average size hands, something that most doublestacks (of any caliber) turn into a challenge.

What do y'all think of my latest project?
Springfield champion loaded in stainless. I just finished completely polishing every piece of the gun. All except for the top of the slide. I left I alone so that it wouldn't glare while shooting in the sun.
Also I just finished making the carbon fiber grips. Well their almost finished. And nevermind the invincible grip screws, they are misplaced at the moment.
