Call it a MASK unit. This faux-military “Minor Surgery” kit from Voodoo Tactical® comes in a 7" x 5" x 2-1/2" OD canvas pouch containing: 6” wound probe; 3-1/2” stitch scissors; 3-1/2” tweezers; 5-1/2” bandage scissors; 5” straight and curved forceps; a #3 scalpel handle with disposable blade; pupil flashlight with mm gauge; alcohol pads; antiseptic towelettes; some 5/0 monofilament; and a gram of antibiotic ointment. And remember: reenacting actual combat surgery without a license is still not allowed.

The kind that you hammer into the ground for to hold up your tent. Make that shelter-half, because these are from Uncle. Measure 12" long x 1-3/4" wide in a V-shape, in olive drab steel with a 1/4” bore for your rope, and shoulders to wrap the rope around. Marked 97403-132227 E0136 MFR 92398, which is a lotta numbers for a tent stake, but that’s the gummint for you.

From the mid-20th-century German military, this is a fully functional field phone. Weighs in at 8.2 lbs, and comes self-contained in a 10-1/4" x 6-3/4" x 4-1/4" dark brown Bakelite case with a handset on a 4-foot cord, a 52” 2-pin jumper, 25” TT plug cord, ringer crank and a battery holder for the pair of D-cells you’ll need to add. Side has slots for the carrying cord that we don’t have, and the inside lid has a full schematic. Should work with standard stereo speaker wire, and we’d get a pair of these phones if we were you. Small quantity available.

Not actually a mystery--it’s one of (4) olive drab polymer paddle-ish things used to hold up mosquito netting over cots in the military. We’ve got the paddles, but not the stakes or nets, so we recommend creating a new game with these and whiffle balls or shuttlecocks in the woods. Or carry them as emergency canoe paddles for when you’re up a creek, or use them as props in a musical. Or you tell us. Measure 29-3/4" long with a 2-3/8” hole at one end, tapering from 3-3/4” down to 1-1/2” with a 6" dia round at the other end.

Talk inside the mask. This microphone, designed to fit inside an oxygen mask, is brand new, made for the US Air Force in the mid-1980s. NOS microphone, dynamic type M-133/U. Manufacturers part # 4500-WBC DLA900-85-C-098. Cable has MIL-C-5898C-WD-34U USAF and U-173/U connectors. Sorry, folks, that's all we know.

This single-earphone 200 ohm military headset straps around your head with a second OD strap over the top from ear to ear, all adjustable with hook-and-loop ends. Manufactured in the mid 1980s in the USA for the US military, we know not which branch. Part #s include DAAB07-85-C-E613 FSCM 80063. Has a 4-1/2" foot cord terminating with a BNC connector.

These gray rubber gas masks from the Russian military fit over your entire head and lend a very insectesque appearance. Eye lenses measure 2-3/16" dia and the front of the mask ends in a snout-like fitting for a filter, which you won't get because we don't got.  (We think it is a standard size) As usual, don't wear these masks into any "situations"--they're for decorative purposes only.

You’ll be needing a Yugoslavian military gas mask, and these are brand new, sealed in plastic with side filters and a “GARANTI LIST”. Plus they’re in a new leather-trimmed 11-1/4” x 6” square olive-drab canvas pouch with an adjustable shoulder strap. None of which means you should use it for a gas attack. As always, these are for display, or for looking like an alien or soldier at a costume party.

But no tent. Or shelter half, as they say in the army, although we don't know whose army these are from.  You get a 3-section, 44" tent pole plus (3) steel stakes, all well used and all in an OD camo pouch. Your bivouac partner is supposed to have the other pole and pegs, so maybe he has your half of the pup tent, too.

Get in touch with your inner Schweizer with an aluminum Swiss military canteen cup. Surplus, and yours might even have a genuine Swiss dent or two. In a perfect oblong, unlike the U.S. kidney shape, they hold 14 oz and measure 4" x 2-3/4” x approx 4” tall with a pair of 2-1/2” folding handles that work better than the U.S. cup handle. All in all, the Swiss seem to have been way ahead of us, canteen-cup-wise.
