This would also be amognst my favorite German WW1 fuzes. The survival rate war very poor due to alloy construction and after being buried a short time corroded very heavily. Obviously this one spent little to no time in the ground. Used primarily on 77mm shells the survival rate was poor at best. To find one in any condition beyond poor would be a rarity in itself. I thought the 60.00 price I paid for it years ago was steep but in retrospect it turned out to be quite a bargain..........Dano
