In 1958, the company hired industrial designer Raymond Loewy to restyle the tractor line, Loewy did away with the smooth rounded streamlined shapes, changing to a bold squared-off modern look.
In a hostile takeover, American farm machinery company Oliver acquired the company in 1962 and promptly discontinued manufacture of tractors in Canada, choosing rather to sell Oliver tractors painted and branded as Cockshutts. Although the tractor above is apparently one of these, it has a serial number tag that indicates it was made in Brantford. I'm sure someone will sort that apparent discrepancy for me.
