WW2 German M40 Single Decal Army Helmet

An M40 army single decal helmet recently discovered in Europe & straight out of the woodwork.Made by Quist with grey rough textured paint finish & a good proportion of the army decal still remaining the underside of the rim is marked 'Q64' with early lot number '353'. The outside of the helmet was wiped over when it was found but the leather liner left as it was found still covered in years of dust & dirt built up over time.
