Help. Unknown clips, parts, 20mm fuzes, partial collection picture

[Stan Smith]

I need help identifying ww2 parts the clips in the first photo they almost look like a booby trap safty clips or something almost like how the landmine fuze safty clip works onky smaller. Then I need help identifying the items in photo 2. The parts F, G, H look like they fit the 20mm fuzes i have in picture 3 and the top thingson F and G come off, i have no idea if they even go in top but it seemed right. H fits perfect in a 20mm fuze so thats why I think it might be connected... I figured so I don't waste anyone's time I'll show in picture 4 a part of my collection but it's not all set up right yet. All but the very top left corner display is part of my WW2 from my grandfather's fuze and ordnance collection he took when he worked at the Watertown Massachusetts Arsenal during the war. All are inerted and some cut aways. I have more to add.

Nice collection,  just curious are there markings on the back of the M1 Garand enbloc clips? also  A, B and C look to be detonators.  C would be for Practice mine fuzes.  I can add a pic if needed.

The safety ring/clip items from your first photo are from the M600/M601 fuze used with the early T7 light anti-tank mine.  Later fuzes used with the M7 series mines had a different safety clip.
