Used to be you could tell where something was made by the metric or standard hardware being used. Now you can't tell at all.
Here in Canada you could tell where a Model T or A was built.
If it was built in The U.S it had straight headed screws, if it was built in Canada it has Robertson Screws.
True there are other things that are different between the Canadian built and U.S. built model A but that’s one of the main ones. Robertson screws a Canadian invention, go figure a one handed screw
