Early MkB42 / MP43 wooden stock
An original, unissued NOS laminated wooden buttstock for the series of 'Sturmgewehr' rifles. This particular one is an early example, with the wider profile, as found on the MkB42, MP43/1 and MP43 variations.
This design was subsequently replaced with the narrower examples (matching the K98 stock profile) to enable storage in existing mounts within armoured vehicles.
A very rare spare part to find!
