Now you must all have a Massey cap of some sort or another. Here's one from my extensive collection accumulated over the years. It was issued by AGCO over here last year for the 60th anniversary of the founding of Massey Ferguson in 1958. They chose to ignore the more significant anniversary of the founding of Massey-Harris-Ferguson 5 years earlier!
OH!!! I have made a big mistake here - this was the French celebration of 50 years of MF in France - SORRY!!
