Starting with the left gauntlet:
Flamethrower
MQ1 keypad cast
Glenross Screw cast
Gauntlet missile
Right Gaunt
Alco Switches
Whipcord Housing
Gauntlet Darts
Oval Piece with indented slot
Ever Ready Mini Torch on/off button
If you really want to be an overachiever, get a mini torch or small LED and install it in the correct spot on the right gaunt.
Redkraytdragon has almost all of these. Youll need to source the ever ready stuff. It's really no more than a textured slide button. Could be scratch built.
The oval piece should be bought. It's easiest. The tube and fittings can be attached several ways. Ive seen (and used) both 1/4" and 3/8" I.D. (inside dimension) braided hose. Look for it in the sink/faucet repair sections of home improvement stores. Use can use either the barbed brasshose spilcer that is with the hose, or you can use a threaded rod that will fit snuggly into the hose. You'll have to drill out the piece that the hose connects to. That piece was not mentioned above, but should have been included in the right gauntlet pieces.
The glenross screw is the dental expander.
