Here is a very nice example of a Canadian No.36 M in the collection of the LER museum. It's not common to find examples with most of the original varnish and markings intact.
F&W= Frost and Woods. No, this one is marked C for Chatco which is the company you are thinking of. I actually have a Montreal Munitions (M) marked example in even better condition than this one but I've posted it before and am just trying to stimulate some discussion.
The Company was FROST & WOOD not woods, they had a large plant in Brantford Ontario, before the war they made Farm inpliments, I have a Tracker Seat made by the same Company.
In the same vein Mills made golf clubs and other out door items before and after WW1
