hello tool talkers, that picture kept bugging me, my mind kept telling me that I have seen that type of wrench.
I had a few moments to myself and looked for info. if you have " The Adjustable Spanner" book by Ron Geesin, look
on page 125, left side of the page, John Henry Morgan, inventor. 1902
that is a very close to what is posted by JPRI, yes, you will notice differences in them. it may be or not be the same invention.
but as wrench collectors, we all, at one time or another found wrenches that did not look exactly like the patent.
at times, an inventor changes mfg's for some reason, and that mfg. might have different ways of making that product, but the
wrench still falls in line with the patented idea.
just my 2 cents for now. Frank
ps, even though it's a new book, I still had to hunt it down, you know where I found it ?? yup, right where I left it.
