A very nice example indeed, although the RA piece is lacking the sheet-metal cover over the bolt mechanism that is frequently missing. The example I have is in much rougher condition: the bluing is mostly grayed, the buttplate is missing, and the cocking lever has been broken and mended by brazing. The last damage is common among several examples I have found listed on line. Taking down the gun is tricky and not readily deduced, so that a common problem for GIs bringing home their trophy after the war was attempting brute force to remove the lever, which is the pivot for the bolt toggle. The right piece, but the wrong method! There is a site online that gives what details exist for this unique gun, and they have an excellent set of photos showing the takedown technique as well as the innards of the weapon. Google ' Walther's Patent Shotgun ' for the URL.
