Mr. Lambie:

I originally went at my query the same way you have approached it and believe this to be the correct approach.

By this I mean that the "Class III" is indeed an indication of the level of proficiency attained.

However, I found a bio on a Canadian padre (McCreery- the last padre to be KIA) that spoke of a "Class III wheeled vehicle", hence my reference to same in the question you saw earlier. I thought this might be a clue but I believe, as do you, that the numerical designation is a trades reference.

I am somewhat surprised that I can get so little info. on this.

Appreciate your insight
