This is an exceptional example of a rare and possibly one of a kind Sheetmetal Walther Prototype Model MP pistol with the concealed hammer. This pistol is pictured and described on pages 80 and 81 of "Walther Volume III 1908-1980, by Rankin. As noted in there, although this example is a sheetmetal design it was actually manufactured in the mid 30's time frame at the same time the Walther factory was experimenting with producing the Model MP concealed hammer pistol. It was an engineering effort by the factory to determine if these pistols could be produced on a low-cost basis using a mostly all sheetmetal design. This effort would later pay dividends in the late days of WWII. The pistol remains totally in the white and is void of any factory markings or serial numbering. As noted in the description the frame was manufactured by using two stamped halves of the frame which were welded together with the welds ground off with the internal parts pinned in place. The slide was also a sheetmetal stampings with an internal rail pinned in place on each side of the slide (noted the raised slide rails) with the barrel and barrel lug still manufactured using the tried and true forging and machining process. The internal parts were composed of both machined and stamped parts. A unique example of complex German ingenuity and manufacturing expertise.

Exceptionally fine as unfinished with most of the bare original "in the white" factory finish. The black plastic grips are in very fine condition showing the early mold marks and grinding on the back sides. Mechanically excellent. The magazine is a crude refurbished replacement. A very scarce one of a kind early sheetmetal Walther MP pistol.
