As a mid 50's St.Gabs' and Lincoln leaguer..I remember the uniform well.
Salt n' peppers or polished cotton peggers with 1" cuff, ankle height and Clark Desert Boots. Thin belt to hold up the trousers. Long sleeved cotton shirt of a subtle pattern, all topped off with the most identifiable three button collar. And sometimes a MacGregor jacket.
Now, if I can only remember what I had for Breakfast.
