So I just moved to a new town, new state, new side of the country, and while taking the baby out for a stroll, found these on the side of the road. (Incidentally they were being thrown out after they failed to sell at a garage sale the day before. My wife bought a filing cabinet at that garage sale and conveniently didn't mention to me there was old climbing stuff there...) They were all tied together with a shoe lace of some sort. I don't know my aid climibing nomenclature too well, but it looks like some ring angles and some lost arrow style pitons, and a whole bunch of early ice gear?
The inscription on all of them says (clearly or very not clearly) U.S. ADC 73
and then there is an M
with a circle around it. On a few of the pieces it says 74
I'm mainly interested if anyonek nows the manufacturer of these. I had a though that they were U.S. Army Defense Corp? Just a guess.
Okay, I'm having problems, inserting images.... here's a link to the photo album:http://picasaweb.google.com/ianchowmiller/OldPitons?authkey=0cw0fnDyvf4
