Perhaps these could be easily 3D printed...
most of you will recognize these parts no matter what beach of service you were in.
The items I'm missing here are the:

1. first aid kit in the plastic box, and
2. good set of tools including spade, axe, (pioneer tool rack) and track connectors
3. Decontamination canister
4. Fire extinguisher (small type)
5. Radio sets from the 80's to current with a wiring diagram for the connectors and what antenna to use.

The good thing about this collection is that most of the parts are universal and can be used for so many vehicles though several decades.

Some of these can be found in spares boxes, but I know proper accurate parts would be great. Hell, even the generic tail lights are different shapes and sizes on kits.

I have yet to find an accurate pintle hook in a kit!

I've actually already done the object in picture #9. I believe it's an overhead light.

#17 would be too small to print. I'm not sure about #8 or 16.

The strap fastener might also be too small. Not sure.

Wedge bolts, hollow end connectors (as seen on M1s to hold the fender braces open) CVC bags and gas masks.

Gunner's (also called turret) tool bag .

Verlinden made a nice set of photo etch tools that were marketed for car modelers. Good set of wrenches and pry bars, but I would like to see sockets and drivers.

The AFV Club and Academy pioneer tools were always enough for me and Formations and Verlinden made resin tools. How about a set with Craftsman logos on them.

The small brass Pyrene fire extinguisher would be wonderful.

Also vacuum operated US windshield wiper motors.

To go with the super detailed workable track: a set of track jacks and end connector pullers so you can show how track of actually changed.

M26 and M26A1 muzzle boresight device and their distinctive carrying cases.

Decontamination apparatus



Wiper Motor (vacuum type, used on WWII through about 1970)

Pyrene Fire Extinguisher - one per US vehicle.
