I recon you are right with the B double idea Swishy, but it is fairly early going by the age of the mighty Mack.

And Canadian as well?

L@@ks like they were into spread bogie drive in Canada

Yes it was a Canadian thing and I believe they called it "Canadian spread"

Brocky mightbe able to share some light here

I can not help much!! Up until the early 90's Canada, especially Quebec and Ontario, had a short spread (maybe about 6-8 foot) rule which allowed higher weight limits on axle groups. Apparently the engineers devised a way to insert a longer intermediate drive shaft and utilized this spread law. They also used 3 and 4 axle trailers with this spread setting between each axle. We used to see some of them come down into the States, But the American spread law is 10 foot 1 inch, so these short spreads did not help. Chicago must have had a similar local law as I have seen tippers and cement mixers with this spread on their drive axles in that area.
