When Nazi Germany surrendered to the Allies, the Whermacht assembled at depots all over Europe and turned in their arms.
Throughout the whole war, it's doubtful a full 7 million K98k's traveled to east Prussia and beyond. Over 14 Million K98k's were built and most experts agree that somewhere around 7 million likely ended up in Russian hands after the war. At any given moment, less than 2 million Nazi troops would have served on the Russian front. It's also wrong to assume that RC's are, in fact, "captures". Many of these arms sat out in the open for LONG periods of time before being rebuilt, so attrition due to the elements was probably a factor. It's difficult to say what percentage of captured arms survived the rebuild programs, but I'd imagine maybe half (or less) would be a good guess. Today, cash strapped former Soviet states are all too happy to sell these to us. Once complete, the whole rifle was generally painted in cheap shellac as a preservative agent - these are often not cosmolened for some reason - crated up and sent to war reserve, especially in the frontier states like Ukraine (which stored them in underground "nuclear proof" depleted salt mines). (Yugos are stamped perpendicular, for comparison)
The rifle's serial number was stamped there running parallel to the rifle's bore line. When done, most parts were electropencilled with the rifle's serial number and a flat was sanded on the left side of the wood stock (think big belt sander and half-drunk worker).
A new (used) bolt was assembled and fitted to the receiver and the whole affair was assembled into a rifle from the binned parts. When the rifles were re-assembled no effort was made to match parts. Those deemed acceptable were retained, those unacceptable were burned. The stocks were also inspected for serviceability. These were placed indiscriminately in bins. Rusty parts were wire brushed or sandblasted first.
The small parts were all hot-dip reblued. Those that were deemed too far gone were recycled into steel for tractor parts or Order of Lennin medals, or whatever. Bores were inspected and those found to be acceptable (ie, some pitting OK - so long as it's still safely shootable, much like with their refurbed Mosins) were set aside. The Russians took all their K98k's, and totally disassembled them except for the barrel. Also, it was a cheap source of arms they could export to allies in North Korea, Cuba, Vietnam, and every other wanna-be commi armpit of the world without depleting their "front line" weapons stockpiles. The Cold War was freezing over and Russia feared invasion from the West. The ENTIRE inventory of German small arms then in Russian possession (roughly half the total wartime output of Nazi Germany's arms production) was ordered to undergo refurbishment and as many useable arms as possible to be made ready. In true Russian style, a colossal public make-work project was undertaken. By the late 1940's, many of these rifles were in an advanced state of deterioration, while some remained like new. Many RC rifles sat for month or even years exposed to the elements. When the Russians came into these guns they stockpiled them and promptly began doing other more important things like rebuilding their cities, etc. The are all WW2 era German Karabiners (though some are former Gew98's the Nazis had converted to K98k spec - rare though!). Russian Capture K98k's all share similar traits. CAUTION: How do I tell if I have a rebuilt RC (Russian Capture) and not an original unaltered K98k? Purchased from person who was selling off collection from his father who was from Hungary.3. The scope mount differs noticably from modern reproductions both in shape and finish. Rifle in very good to excellent overall condition. Very clear optics with original type scope covers. Wood would be considered excellent !! ZF4 scope by Voitlander (ddx) is also very good with the engraved marking of KZF* on leftt side. Rifle is in very good original condition with good bore & much of the bluing remaining. These rifles were considered to be experimental & very few originals are known to exist highest scope mounts numbers recorded during KCN collection of information for backbone of the Wehrmacht was #30 but the opinion was & according to German information available many more were probable made. Has the ultra rare swept mount(No 88 base & No 88 scope mount). #118 – This 1944 Sauer (CE) sniper rifle came from a Hungarian collection and looks to be all original.
