I'm not really replying to the correct post but I can't find the reply button on your last post.
However you asked where I had got to on wrenches. I have written up the list of part numbers and photos where I have them on M-H wrenches. I will leave this list for now and continue with M-H-F, J I Case, Johnson Harvester etc.
I haven't seen any Wisner or Patterson wrenches in my research or any by The Massey Manufacturing Co. or A Harris and Son. If anyone has any information on any of the about it would be most welcolme.
I'm not getting on as fast at the moment as I should as there are so many other things to do like Newby Hall and Paisley. Hope to see you there.
