Built in Drummondville, Quebec, Canada, by FBM Manufacturer Inc / Edgar Machine Shop. The company eventually became Terra Jet. The 3-JET was only produced for a few years and Terra Jet was sold to a US owner.

Unfortunately, not much info out there on these units. I tracked down an individual that claims to have all the info and specs, but refuses to release that information.

So if you happen to have any info, please reach out!
