Could someone ID these please?
Any idea of value, need to sell them and don't have a clue.
6 inches by 5.5 inches in size made of steel.
Thanks.
Dave.

looks like the lid of a box. the center lifts up drawing in the ends of the long strips. When the lid is lowered on top of the container and the centre released, the long strips slide into loops at the corners and then either the centre is twisted to lock it all into place or there are screws that twist to lock on the corner loops. Can't be certain which box this is from but H60 is an example of the type
 
From their make up I would say that these are the lids from Slab Demolition Wet Guncotton containers.
The slabs were kept in a metal box with a spider lid and had an inspection window in the side of the box to monitor the liquid level which had to be topped up if it fell below a marked level.
They were replaced by Slab Dem 1 lb CE/TNT in the late 1940s early '50s.
 
Further to my last. I find that Slab Dem CE/TNT 1 lb issue started about 1943 and would have been the slab of choice to those at the sharp end i.e. Royal Engineers, SOE and other clandestine organisations. The Wet GC slab was nowhere near as powerful as the CE/TNT slab, furthermore, it was liable to deterioration over time, so was not that reliable.
I looked at a 1960 publication and amazingly it was still there, although deleted, but left in the book.
You can clearly see your lid. I thought that is what it was because of its size and what appears to be a rubber seal around the edge.
Depot demolition grounds were littered with white cellulose block pieces in the late 1950s.

Thanks AE501 that's brilliant information.
That's what amazes me about this forum, we come up with the strangest most obscure items and someone out there works out what it is, a fantastic on line resource.
Credit to Spotter and co for running a great site and to AE501 for identifying these metal plates.
Dave.
