K power socket cable Germany NOS

Original German K power socket cable in new old stock (nos) condition. The black power socket is stamped with “K 8933” and it is mounted on a 2,5 meter cable. The cable is protected with a single fuse box. It works with 6/12V and it can be used with old small size 1 cm diameter plugs. The last 2 pictures show the sort of plugs that fits in this power socket, but the plug is not included. Very well made in Germany.
