Believe JW means a Midland unit.. Similar in operation to the Bendix Hydro-vac. Believe Fords stuck with Midland remotes and and also had an underdash unit by Kelsey Hayes. Studebaker and others used the Hydro-vacs in many models of that mid 50 early 60s period.
Both need a regular master operated by the pedal which in turn activates a remote cylinder. That is tied in with and works the main master as well as an aux vacuum control setup to work the power booster. Since the pedal operated master is tied in with the main hydraulics as a backup in case the booster fails, believe pedal ratio is still a concern.
Here is the TBird version of the Midland.
