Hello group,

Our '72 has 4 bags on the rear axle, 2 forward and 2 aft.  Picture attached from last years brake overhaul.  One of the very few records that came with the coach was a receipt for 4 new bags in 1999.  The bags do not appear weathered and hold air just fine, however they are getting old and I'd like to carry a spare just in case.  (we'll be going to Lexington at the end of March for "Road to the Horse")

I cannot find many markings on the bags other than that they are Firestone AirRide bags, they have the letters AY and an H and one bag has a T200 stamped on it.

Does anyone know what bags were used on this vintage coach?  It sure would be nice to not have to tear it all apart just to get a part number....like just about every other system I've needed parts for

Anyone have any Newell documentation on their 70's vintage suspensions?

I'm curious what pressure was used for pressurizing the bags.

One of my summer projects will be to remove the compressor for rehab of the compartment, the wiring, the compressor and to replace the leveling valves.  I just finished replacing the reservoir air tank on Tuesday.

I threw in a picture of the cast iron compressor which was from the day we bought the coach.  Things are much cleaner now but I don't have a more recent picture.
       

Thanks for any help and advice!
