Gang,
Just wanted to share an unusual wrench I ran across this weekend at a sleepy little pawn shop. This DBE wrench is unusual in several ways:
1) only one end is offset,
2) both box ends are the same size (9/16", 12Pt), and
3) the offset box end is broached deeper and is a different shape than the non offset end.
Here's a couple of pictures for your inspection:


I've never run into this wrench pattern before, but AA indicates this pattern was popular in the late 1920's thru the 1930's. AA also indicated that several OEMs, in addition to Walden, produced this patern of wrench.
