I have a fair number of the hexagonal shipping plugs from WWII USAAF bombs, which seem to fall into two distinct sizes.
There are the larger ones which are 2" across the flats of the head, and just under 2" dia. on the threads, and there is a smaller version which is just over 1.6" across the flats with a 1" dia. thread.
I've gone through the relevant manuals but none identify the diameter of the fuses, so can anyone identify which bombs had which size holes?
I found a few more today of the less-common types of the larger patterns, circular headed with a pair of flats, and a single circular one with sloped sides and a slot across the face.
I'll try to get some photos posted soon.
All the best,
Paul
