My 2020 calendar has a Rockol B 77 Tractor pictured for June. Internet info says it was made in Winnipeg, MB just after WW TWO. Anyone know more details? Or have one of these or know someone who has one?
The calendar doesn't say who owns the one pictured.
 
That's interesting, I have heard that they were made in Edmonton, Alberta by the Rock Oil Company. There were a lot of very similar tractors on the market after WWII using mostly war surplus Dodge truck components including the engine, tranny and differentials. Two similar makes that come to mind were Simpson and Jumbo I think, plus several others. There are some of them in this area around central Alberta.
 
There was a gentleman in the coldspring Minnesota area that had one. Seen it at Albany pioneer days many years ago. Got a picture of it somewhere at home. I’ll have to look and see if I can find it.
 
after my post here I looked further on the internet and found an article in Farm Collector magazine and it mentioned the fellow from Cold Spring, MN
