Mate I ain't gonna bother with percentages etc. I leave those sort of things to students and bofins who have a lot of spare time in which to work the buggers out. But....
Rarest of the rare....Cab 11 either make but especially Ford here in Oz. I saw the remains of a Chev one go through the crusher at Ken Hughes at Kingaroy a few years ago. A lot of people must have looked at it and thought it too far gone or to expensive for what was left of it. Max Hedges here on MLU has a Chev 11 cab at Yass, NSW. New Zealand seems to have the remains of mainly very early Ford 11 cab trucks...the one's with no front vents.
Cab 12 becoming rarer as they are older and had more weak points especially in the windscreen frame then the Cab 13 plus were cramped in the cab department making them harder to drive. Most of these returned home with the troops from North Africa so saw war service in the desert. Most were issued to our troops by the British then 'onsold' to the Australian Government
Cab 13...good one's becoming hard to find but you are more likely to find these as they had more cab room and were easier to drive because of it. Some remained in service till the 1960's with machinery and special type bodies on them. Most were sold direct to Australia and were assembled/built here at several different locations, especially Chevrolet with plants at Brisbane, Sydney, Melbourne and Perth to my knowledge.
Hardest piece to get for all models...the original type rear bed/body/decks or useable remains there of.
Rarest complete model of them all the gun tractor versions whether British/ Canadian or Australian in all cab models and either Chev or Ford. Most had the rear boddies cut off to make them flat decks for the carriage of hay etc. Then I'd say the Chev C60X, 6X6 would be ralatively rare as well as not many were purchased. No Ford F60H, 6X4's are known to have come to Australia. Rarer then normal are the vehicles fitted with a genuine CMP winch as only a certain percentage (that bloody word again
) had them. Here in OZ you are more likely to find a 13 cab 15cwt 4X4 or a 60cwt (3 ton) 4X4 long wheel base as these were used as the General Service (GS) trucks and there were more of them originally.
Don't look for an original Dodge prototype CMP because as I said elsewhere only one photo of it has ever appeared and if one of our Canadian members even knew where one was we'd either never be told or they would crow about it forever
Now can you remember all this student Lionel?
