Alan,
Just bringing your wrench thread back up the list a bit, hoping we can get some of the new viewers to help you out with your mamoth project, I am sure many M-H collectors will want a copy of your extensive research, it will be a new form of information which every Massey Collector will need for quick refernce.
It seems to of gone very quiet for a while so here is another photo of the M-H No 2 and 3 tractor wheel lug wrench, come on other viewers please post your photo's of your unusual M-H and related Companies wrenches to help Alan along.
Malcolm.
