Massey Harris Trucks?? (1920's To ???)

[Bud Tierney]

In the course of looking up something on a Massey Harris 101 tractor (there were Jr's and Sr's in the 40's) I found a couple references to Massey Harris Trucks:
A: 1930 McCord shows (after Massey Harris tractors) a Massey Harris truck ( no model #, no yrs, no tonnage) with a Cont S4 4cyl;
B: 1979 Fel-Pro shows (under Massey Harris Ferguson):
101, 101JR (Truck)
101JR (Canadian) Truck (these two lines in one listing segment, showing using Cont F124, F140, F162, F4124, F4140, F162 engines, all 4cyl)
NOTE: Cont "F-124" etc are farm/ag/maybe industrial designation; "F4124" etc are Cont "automotive" (i.e., truck) designations.
C: also in separate Fel-Pro listing segment:
101SR (Canadian)
Truck (these shown with Chrysler Ind 6cyl)
Various Massey Harris histories, comprehensive as to tractors, including the 101Jr and Sr, don't mention any trucks. Massey was a Canadian outfit, and any trucks (if any?) might've been sold only in Canada.
Anyone have any knowledge of these, or suggestions as to sources to check??? Any comments appreciated! Many thxx!! Bud
