I just posted a new ad on Airstream Classifieds.
These are the original-style propane tank valves, not the newer OPV. I really liked them because they both have gauges that indicate the true amount of propane remaining in the tank. The gauges are not compatible with the newer OPV (overfill protection valves) style.
If you want "original" for your vintage Airstream, these are the way to go. I've never had any trouble getting tanks filled with these old-style valves, as long as you go to a propane dealer. Propane sellers, like U-Haul, balk at filling tanks with the old-style valves.
Price is for two (2) valves with gauges.
