JAWA type 15 of 1952. This is a 500cc OHC 2 cylinder.

Unfinished restoration. Previous owner wanted to build a cross bike of a JAWA 500cc OHC. This project consists of a not complete bicycle part with a reconditioned engine and 2 extra engine blocks which are partly disassembled (in the boxes are the parts). The block that is now in the frame is not the original one with the right numbers but the matching number block is there. Nice project to build an off road motorcycle or to restore the original.
