HI,IM UNVEILING A helmet that ive owned for over 6 years now and tried selling on the brisbane military circuit for $90 for the ;last 4 years(thanks for not buying it as i really would have kicked myself..)you are looking at a helmet which was stamped(ca,350 times with over 50 different sized rzm stampes from 1/8 ich to the size of the helmet!!!!!!!)it was stamped as a sheet of metal on both sides and they were made for the helmet as all the stampes are the "right way up" which means that when it was a sheet of metal the bottom of the rzm stamp to the outer bottom..ive counted over 250 stamps but i got sick of draw3ring them(i used water based paint which can easilly be washed off)but the inside still has to be marked out..i wanted to find all the stampes and give it to a proffessional restorer/signwriter to complete the helmet,remove the fake decals, mark the RZM stamps out in 3 different colors as they overlap each other many times over,i was going to use yellow for the biggest stamps orange for medium stamps and red for the smallest but i need funds for a new project so i need a price guide(i will pay for an authentication for the future buyer before any cash changes hands and they can choose the dealer to authenticate it).i dont know if it was like a rzm/patent piece but seeing that it is totallybattleworn(the most worn helmet i own)this helmet saw some real action.green paint ,the ss decal swastica and shield are cheap repros.but besides that the helmet is 100% factory original i will stake my reutation on this!!please let me know what you think and are there any museums or such which would be interested in this piece(i think its too much of a shame to sit in 1 collectors collection)i am fairly sure that this is the only one in the world.but i would take a mint sd m42 in trade:othanks and best regards from brisbane andreas
