The grease seal C31UCW 104180 is found as a part within CTL 814 SA, Seal Assembly - Bogie Wheel Grease

You will not find this part or assembly listed in the May, 1944 edition of the Ford Canada Illustrated Parts Catalogue for Carrier, Universal MKI* and MKII*. It is listed in the July, 1945 Ford Canada Illustrated Spare Parts List for Carrier, Windsor MARK I*

As the first model Windsor Carrier was supplied with standard CTL 94A wheels, the assemblies could have been for that model W.C. The second model W.C. also had the same grease seal assemblies, but the C49WC 108120C wheel and tire should stand out due to the increased width difference. The Windsor Carrier contract was a single order produced for UK Supply Ministry.
