Thx for these pix!
Charlie I have never seen that brush roll before!! I think you did note all the differences except one that I am aware of -- the early one with no clean-out, no reset button, simpler lettering, also has a gray plastic roller on the bottom instead of turquoise, as does my early version. This is a hold-out from the model F PN1 that has that same gray roller.
btw my earliest G PN1 still has the long, single cord with clip-on clips. Those are pretty hard to find as most of them were upgraded later when the newer cord with the rubber straps and the handle plug/socket connector were introduced. See how even yours has been upgraded -- I can tell without seeing the entire handle because the cord coming out of the back is turquoise -- the earliest ones were gray, same color and material as the main power cord.
My understanding of the Hospital G was that it WAS intended for hospitals -- The "sanitary" filter and all that, and also that it was so quiet in operation (without the PN, at any rate) that you could vacuum in a room where someone is sleeping and not disturb them, e.g., patients in a hospital.
