Thanks for the detailed info. I'm always learning.
Jordan, thats an English clutch pedal(with welded on strips of non skid) in your 2nd photo. Have you a picture showing the bed rails of this carrier? This would confirm its origin. (what about you Phill?)
I make the assumption that the clutch pedal is English, because they are the type usually seen in the hulls with the sharp edged (channel) bed rails, as opposed to the chequer plate type pedals seen in the Canadian hulls with the rounded (roll formed?) bed rails. Another difference between the two, is the lock out lever for reverse on the gear stick. one is a short rounded alloy casting, and the other is a longer skinny steel lever.
another question I often have often wondered about, is the manufacturing differences, between the various British manufacturers.
Phill. Please ignore my statement that your early production carrier is of Canadian manufacture. I was looking at
the photos of your later(missing front armour) one.
