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.
US Navy Mk1 Mod5 gunsight reticle. In classic "ladder" pattern. Came to us in a lot of antique 1940's Eastman Kodak Military grade lenses and reticles. This unit was part of an illuminated cannon sight or gunsight. Might be a bit dusty or tarnished, but still looks pretty good for their age.
Or peg o’ our tent, or something. Our each is a set of (6) aluminum pegs, 10" long x 1/2" OD x 3/8" ID cut at 30 degrees at the bottom for driving-into-the-ground efficiency, and drilled at the top to take 50 feet of 1/16” dia white nylon polyester rope (included). We’re pretty sure this was all used to stake something down, we just don’t know what. Whaddya got?
