I have noticed several of these with a small steel pin protruding into the interior of the fuze. It seems to fit into the split in the outer setback ring on of the percussion element. Most of these fuzes do not have this and the slit on the setback ring is too tight. I suspect this feature was more or less useless and dropped. I don't really know what it would accomplish other than to hold the internal parts steady ? I have noted two like this, one marked V.S.M. the other unmarked and on an E.O.C. projectile. Has any one else found this kind of fuze or have any thoughts on when and why ?
very easy to miss unless you are putting in the internal parts and wonder what the obstruction is or you actually look for this pin.
