HECKLER & KOCH HK4 .22LR CONVERSION KIT

I have a Heckler and Koch (HK) GmbH. Oberndorf-Neckar Germany factory original .22lr conversion kit for the HK4 pistol. Comes in an original HK factory black cardboard box serial numbered to a pistol “22915”. It is marked on the lid “Heckler & Koch GMBH Oberndorf/n. Germany” in black on a green label. The box has cutout spaces spaces for the kit which includes a .22lr barrel marked “.22LR”, “HK”, “Nitro-proofed eagle”, and serial number “109185” with recoil spring, a red handled hollow screwdriver (called a factory “tool” by HK) with black cap complete with cleaning “chain” and little metal rod for holding extractors when changing from center-fire to rim-fire, one (1) .22lr 10rd. magazine with black finger-rest floor-plate marked “HK .22LR” and “11/74” on the side of the magazine body and the original test target dated “20 August 1976” showing the .22lr barrel serial number which corresponds to the pistol serial number which is marked on the outside of the box. Like-new condition with minor handling/usage marks. The barrel is in mint condition with a bright and shiny bore. Rare and almost impossible to find in this condition. (Shipment to Alaska, Hawaii, and Puerto Rico requires additional shipping charges due to the much higher costs of delivery to these locations). 3-day inspection privilege (return shipping costs are not refundable).
