I also bought this, a 1918 Exploder ~

I'm a sucker sometimes for ww1 material, especially things I never had before and this was one
such item. Is it worth much ?, weighs a ton of course.

I alsow picked up a Ross bayonet dated 1911 (which is tough year to find) though it had the unfortunate 1915 clip
to the blade and a 1916 sighting scope tripod. These last two were also very fairly priced.

When I joined the army we used an EDC (Exploder Dynamo Condenser) that weighed about as much as a large car battery. I was pleasantly surprised when, a few years later, the EDC was replaced by Shrike, something much smaller and lighter, that could fit into the pocket of a combat jacket. Not sure whether Shrike is still in use or has been replaced with something else.

I love those machines, I have a couple myself. This one is a Dupont.

I've got 4-5 of the large style "Hell boxes" and maybe a dozen or so of the smaller ones (twist type). They are generally categorized by their capacity, with the large wooden ones like this referred to as 50 or 100 cap machines and the smaller ones as 5 or 10 cap machines. I'm at work today so cannot take any updated pictures right now, but here are a couple of old pics from 6-7 years ago before I consolidated things a bit more.
In the US the prices on these are oddly inflated, driven by collectors of mining equipment. A typical 100 cap blasting machine in good condition will often reach 300-500 USD, with better condition or specialty items going higher. For the ordnance guys one of the more desirable ones has the ID tag like Gordon shows marked as for the Livens Projector - one I've yet to find.
