The fuze's base is hollow so you don't have a perfect force in one direction. It's blown up like a balloon and you see this effect on so many other...

Hallo, the "Leuchtspurbrandgranate"(Incendiary Tracer Shell) seems to be a late war introduction (1943). It was supposed to be used together with...

No. You CANNOT have deformation in one direction without deformation in the other direction, because that's just simple physics - if you squish...

Here is some more information. The Tin case was replaced by a brass case certainly by or before this book was published in 1896. There is also a...

I have the exact same drawing and what you posted here is the blank from which the adapter/socket is machined. You should have posted the one below...

The 0.75" dimension is from the top edge, or rim, of the socket to the inside surface of the base of the socket, as per the attached image. The...

It wasn't just heated. It was heated and - if a No.80/44 + No.44/80 combination - subjected to an explosive shock wave, followed by the impact of the...

Looking more closely at the mess of numbers on that plan it turns out we both might have read it wrong and the "0.75 in" could be the depth of the...

Now it being a No.80/44 makes sense and I also thought of it, although i'm not sure how to tell a No.80/44 apart from a regular No.80 in the absence...

This is on eBay - not sure if it’s the right thing or not ...

A good expertise here, and nothing about a M39 https://www.bergflak.com/index.html Moreover, there is a contradiction in the documentation...

Thanks so much guys for sharing the pictures! I have never seen one before. Jason

Not necessarily. This No.80 doesn't show the usual marks of functioning of a Shrapnel shell, but more those of a timed HE. So a possibility is it was...

The 0.75" dimension is from the rim edge of the socket to the inside surface of the base of the socket. For the 18pr Shrapnel shell, the height of...

Well, I think you're right when it comes to this fuze having been subjected to a large force from below, which I take as the shell exploding and...

Thank you! That is indeed very useful and I'll absolutely post pictures of the finished articles. Ah. I got the dimension by measuring one of...

Hallo, I looked up some old german airforce manuals to find this strange 20mm fuze. All I could find are a tracer (Leuchtspur) and a dark tracer...

I am out of my depth in this discussion but I have no references to a red projectile existing as incendiary/phosphorous. I only have seen blue...

Nothing ? Is it a mistake in the Bulletin 59, 1944 ?

Thanks The only problem is that the AZ 1528A is on a red projectile( see above) , not blue! I was told that this is early phosphorus -1941. It’s a...

Overall length of the HE shell is exactly 7 & 3/4" (196.85mm). The fuze socket adapter on the shrapnel shell is dimensioned as 1/2" on your drawing,...

I've managed to find the dimensions for the 13-Pdr shrapnel for myself, from a 1917 American book named "The Manufacture of Artillery Ammunition"...

Heres my Tin,,,,,,,, Dave http://www.millsgrenades.co.uk/images/soe/Tin%20of%20tyre%20mines.JPG

Exactly, I misunderstood your question. But I hope you will enjoy the photos none the less.

I think I've never seen a German M39 HE mentionned in lexpev site (I assume different from Nb39 and Norwegian M39)

Is this any good. Cheers Andy

I do not have the dimensions, but hopefully the photo can be of use to you. The M39 is a smoke grenade but you properly know that. Or are you...
