TOC etc. bike stands

Here are some stands I picked up from a private collection in Toronto. I've sold one Myers A frame stand & and the larger drop stand. One stand(second photo) is a 1911 patented Persons. Unsure of the smaller drop stand maker. Anyone know if these (with the exception of Persons) are Canadian made?

I also have this.  It stands 35 inches tall. I think it's one of two used to elevate a bike on a showroom floor. Not certain. Canadian?
