Picked up 2 interesting wrenches today.
A Maxwell 2 (don't see many of these), and a Vlchech V notch 7/8 x 1 DOE. Not stamped but flatter than most wrenches. AA didn't mention this wrench.
Also picked up a couple of stamped wrenches in a thrift store the other week.
2 with no name, and the other marked M in a diamond no. 275 , so likely Mossberg.
Since I'm here, I included an user bent stamped wrench 7 & 8 on the openings, a ForAFord and a Wakefield no. 45
