Peep!
im new here and know nothing about lugers or guns really, . looks like a dwm 1918 on the right side with those 3 little cartouches and the date on receiver. looks like a replacement barrel cuz the numbers dont match.
dont know why the sideplate is x'd out , mebbe rebuilt ? again Im stabbing in teh dark but its just for fun right
. Double dates are marked 1920 to prove they are government property. I need to take a nap now my brain hurts.:P
I wonder why the numbers arent square with each other on the 1920 you would think for the energy you were putting into it you could at least eyeball them a little square'r.
