NOT ANY GIBBS CARS I KNOW ABOUT ---heh ---except the LIRR Gibbs MP-41 cars which featured Low-v control according to LIRR tech records ---IRT Hi_V cars used the cheaper H-v control (no extra circuits, no batteries for control circuits, less hardware on trail cars etc.
Ask Mr. Tibbets of Seashore museum who 'WAS' working on THE ONLY IRT GIBBS CAR left in existence (or WHEN he was working on it at Seashore Museum--heard a while ago that he got PO'd and stopped working on it some time ago - maybe someone can update on THAT)---
Take the old Gibbs out and fire her up, and wrap that huge Hi-V controller around ALL THOSE CONTACT POINTS & see what happens.....
besides blowing a cartridge fuse as thick as a salami loaf,,,,,and smoke, and a report sounding like a truck backfire with your ear net to the tailpipe !!!...yeah, wait till Big Ed hears about a " Hi-V" Gibbs "wrap around" - (heh heh heh heh)
