My Father-in-Law owns (or owned) a book of pictures celebrating 125 years of Canada, and in there is a picture from Saskatchewan in 1952, of an RCMP Officer shooting cattle that were infected with Hoof (Foot?) and Mouth disease - with a No 4.
CANADA: Cattle Crisis - TIME Life Magazine March 10, 1952.
I'll try and see if I can abscond with that book when I visit next, but if not, that issue of Life has the picture.
I also have an RCMP Longbranch - now that I can say it's the gun used n that pic it has doubled in price!![]()
