A time proven design from French company Campinggaz. This particular example was found in a thrift store and dates back to January 1981. It was still in its original almost unharmed packaging. This gas burner head was designed for direct mounting on top of the 901, 904 and 907 refillable gas canisters. The smallest version, the 901, is out of production or isn't available in some countries any more as far as I know. Later versions of this model had a build in wind shield for better performance. On the pictures I had it mounted on a 901 gas canister. These can still be found at flea markets or in thrift shops. For size reference I placed it next to a classic kerosene stove.
