Hi there, I've got a New Britain wrench that's 11/16, same style... looks like some great wrenches to collect. This one reads "NDF-60- 11/16.
I don't think you're looking for the double open ended wrenches, but I have a nice one that's 1 1/8 and 1 1/16 of the same era (NDF32).
Now that I'm looking at it, the 11/16 wrench is a pretty damn good lookin'!!! Maybe I should go on a date...... I take all too much interest in wrenches!!!!
No, but really, it is a nice wrench.
If you'd like to have it, I'd give it/ well, sell it, for three dollars plus shipping. Anyhow, let me know. In the mean time, I'll look around for some others. But, I think the only other New Britain wrenches I have are either open ended or offset socket type wrenches. But, I'll look around. My family makes fun of me for all of the tools in my house. I always tell them, "Well, at least I don't collect cars." Usually, that shuts them up.
Anyhow, I'll keep looking.
cheers, bird
