Jim, I think you are heading in the right direction to modify an existing jack with the features that make it identical to the issue Canadian C01UC series jack. As your carrier is the Windsor, Canada production, it would be great if you could get the same body with the maker name and patent date. I believe the originals have the end track link hook pinned in place vs welded.
Regards the item being offered on eBay, it is not something you see every day. Is it the American production track jack for the G-166 Mk-I/MK-II T-16 U.C.'s out of Somerville, MA? The wider, shorter rod, and shorter track 'horns' suggest to me it is a G-166 tool. Similar principle as the C01UC and C31UCW series, same sub-contractor, but different.
Does anyone know if the British production U.C.'s had a similar track jack tool? Are there any images of a 'British' one in use, or are there any images to show the part numbers and other casting marks?
