This is a Coleman 286A703 dated made in March 1989. It is "dimmable" by use of the control wheel. Found in Australia. It came with a Schott glass but I exchanged it for a Coleman glass in later photos. The colour is a darker red (almost maroon) than the standard red Coleman colour. It is quite variable visually depending on ambient light. The following photos are after a light clean up and test-firing it. "3 89" Cheers Tony
