I was at the flea market this weekend and came across a guy with some very nice old tools. Apparently he is thinning out his collection. Most of the prices were pretty normal, but he had 4 tiny wrenches layed out. I got 3 of them for a dollar and was quite content.
Here is the only one I found particularly interesting, the other 2 were pretty typical.
It reads on one head "Dura-Chrome" (which I recognize), "Forged in USA". On the opposite head it reads "1821" ... What does that mean?
On the other side, both heads are marked 3/8.
What is up with it? Why are both of the heads the same size?
