I have 3 speed wrenches for sale.
The rusty one is 3/4 and 7/8 inches only. The 3/4 sockets are on opposite ends of the wrench and the same for the 7/8 sockets.
The shiny wrench with the knurled crossbars has 11/16, 3/4, 13/16, 7/8 socket ends
The shiny wrench that has smooth crossbars has 3/4, 13/16, 7/8, and 19mm ends
I don't know what that attached socket is for but the nut end of it fits snugly into the 3/4 inch socket end of the wrench. I have no idea what the square thing is on the open socket part of it.
