A U marked Luger

Hi all.
I posted this on Jan Still's site and it sorta petered out. I thought that I might get some new blood here to comment on this pistol.

Just picked this up. Sorta odd markings so I thought it would be worth a little research. The finish is sorta matte, parkerized perhaps.

Serial is 4006. No letter following. All marked parts match.
4 Digits are on the front of the frame and on the bottom of the barrel and on the left side of slide
2 Digits on the side plate (marked twice, side and bottom), take down lever, safety bar, safety, trigger, center and rear toggle, trigger bar, Mag release. I did not take it to pieces so I may have missed something.

The toggle has no makers mark (though it has the 2 digit serial). Barrel has an eagle on the right side and also an eagle with the numbers "63" on the left side, near the breech at the 10 oclock position. This is very light, the "3" could be something else. There is an eagle stamped on the side of the front toggle. Just forward of the SN on the slide is a stamp of what appears to be a sunburst.

On the top of the slide, where you would expect a date is a "G" and above that, an elongated "U" surmounted with an umlaut.

The grips are plastic, someone at the show said "Russian". The mag, while not matching, is numbered 4026, 20 away from the SN of the gun. Also the mag has "2/1001" stamped on it.

There is a numeral "4" in white ink on the right side of the receiver.

I am posting some pictures. If there is anything else that would help identify it please yell.

I am posting it here because of the "G".

From my poking around on the Interwebs, it seems that Lugers marked "Ub" were used for various internal applications in the Mauser factory. Some were used for pressure testing, some for accuracy testing (this one seems odd to me) and some, I suspect, as bench samples to show correct fit.

The one I have is marked just "U", I have seen no other examples like it. The parts are finished and, as I have said, all matching (n.b. the firing pin marked but does not match).

The barrel is pretty darn pristine, not the appearance of something that was fired a lot.

I am interested in your thoughts and pardon me if you have seen this on the other board.
