US Bombfuse " Air propeller "

If nobody has it by then I'll try and hunt when I get home later.

Just too late, I have find the same doc as Hazord.
The air vane can be part of any US modern tail fuze.
I'm particular looking on air vanes with holes in the vane !

Hi Yoda, this seems more like it,
the stem cup is gone so it looks strange.
The holes in the vains are square, ill post some more pictures this evening.

Here are the pictures,
The holes look as if they are punched square!

I've been through my pubs with no luck, noting the irregularity of the holes, I wonder if they were done post-manufacture? It could have been a field modification, or something done even later - ?

Could be, i think also but the vaines are bent in the opposite
direction than al other ww2 fuzes, so this is strange i think.
I can nog find any with the bending this side.

the vanes do belong to some sort of US 100 series tail fuze, thats possitive, I've seen them with and without square hole in the Vanes, it could just be from what ever company made that fuze as long as it met the mil spec. Lots of time we don't use it as an ID feature due to the fact most arming vanes are destroyed after impact.

the punched holes look off center. in 60 years alot can be done to a fuze

Thanks! the holes are indeed off center.
The piece has no markings.

So in the 100 serie i need to look?

Another point is that you can see the normal arming wire holes, round and neat, closer to the stem. It would make little sense to have trim factory holes and then in another manufacturing step punch rough, off center holes.

Let me think,
if the blades are bent otherwise will say that the vane shall not unscrew and deliver the firing mecanism but well screw the arming rod in the fuze. Why ? That do me looking on UK Pist No 37 for squash the chemical glass.
I have not my Doc at home (where I am now!), look perhaps in this direction.
Other possibility, the thread of the arming rod is counterclockwise (we say lefthand). And I have also the same idea, the first amelioration of Pist No 37 when the pistol was unscrewed of his pocket fuze with a normal vane.
