Hi
The most stamps found regulary on fuzes are shown on my N°103 fuze, and on rarely like on my N°102, I've also more N°102 with good way swastika than reverse....
The reason why i think they are two different acceptance inspectors stamps (If not What is the other contactor for the reverse mark.....)
If the reverse swastika is G D Peter's who had the forward swastika? If the first is recorded the second must also be somewhere.
