Here's my collection of Williams obstruction wrenches. To be honest, bonneyman got me started on these. Earlier in the thread (reply #13) he posted a photo depicting his Williams obstruction wrench collection. I liked the wrenches and thought I'd make a set of my own, so I got started on it. Well, completing the set is going to be a lot harder than I initially thought it might be. They're not very common and I think there's at least thirty SAE variations, as well as several Whitworth and metric sizes. I’ve never seen a metric version. Anyway, after a few years of collecting, here's what I have so far. Included in the photo below are three Whitworth wrenches and one factory "Special" wrench with openings of 7/8" and 1 1/16".

I am not familiar with the brand of masonry tools you're referring to, but I was curious enough by the name and the unmistakable Williams logo on Provincial's find to check through some catalogs (finding zilch) and to get some google-fu going, where I found a reference to Blue Banner Tool Mfg Co, 1213 East 83rd Street, Cleveland 14, Ohio, in Hardware Age, Vol 186, Issues 1-2, 1960.Is the name related to the brand of masonry tools is the question.
I found a couple more since I last posted a few months ago. These wrenches are tough to find!
