Looking at old prices is fun. I remember old shooters talking about surplus 1911's going for 12 bucks. I don't know if that's true or some legend. It wasn't until the 1970's that my gun ownership went beyond an H&R 929 for attempts at plinking (and damaging my hearing), a .22 rifle for squirrel and a 16 gage for rabbits and pheasants. If there were deals out there on milsurp, they probably disappeared before that.
The real value of something for me is how many hours I need to work for it. In 1973 I had to work just about as many minutes to but a gallon of gas I do today. For a Ruger Standard Auto, I had to work about 1-1/2 hours longer in 1973 than I do now.
The place I'd take a real hit is gold. The largest piece of gold I own is my wedding ring. It will probably remain that way because I'd now have to work over 4 times longer to buy an ounce than I did in 1973. Thank Tricky Dick and the crew for that.
