Propane sensor/detector 1980 FC33

[Robin]

Just checked out my LPG system. Seems to work as designed generally. I also
checked out the original LifeGuard LPG and CO detector system. I tested the LPG
detectors with an unlit propane torch. None work. One is absent and one is
melted. Did a search and found this set of sensors
http://www.futurlec.com/Gas_Sensors.shtml but they do not look at all like my
little white plastic roach hotel style sensors. Are the original ones
available? It has only been 29 years.
