Again, i write my name with 2 x P at the end before we get any confusion ; - )
I bought it here in the Netherlands from the son of the dutch army officer how fought at Nimegen, Market Garden Operation. It's signed on the back with Brettschneider and i found that name on this picture with the help of a friend. He apperemtly lost his watch at the Nimegen operation but became later after the war the initiator and trainer/founder of the east german combat swimmer....
Watch is still all original with it's first blue hands, amazing reddish radium that comes through the sandwich dial and it's original glass, movement only needed to be cleaned and i put a old bracelet with orginial clasp on it. Not wearing it a lot because of the radiantion danger.
For more info about vintage panerai, two german collectors just wrote a very interesting book that can be seen and ordered here..
