I do not know the age of this nice little 1 Pint stove, but suspect that it is late 1950's to early 1960's. Since I acquired it, all that I have done is dust it off! It was full of fuel, so drained it and put in fresh kero and away she went. Never even had to change a seal. The tin is in very good condition for the age, so it would seem that this has been kept somewhere warm and not stored in a damp shed or garage. The windshield and the spirit cup may be copper, or if not, are very dark brass. It has the Townson & Coxson (patented 1943) removable screw that allows direct access to the burner nipple (What a great idea!). It also appears to have been sold with a Pilot Light as part of the outfit, as most Burmos 21's that I see have one. What is really nice, is that the lacquer is still intact, never been polished, and the decal is almost totally complete. The lacquer being still intact, shows that the untidy solder around the filler cap tube is from original manufacture, not a repair (which is what it looks like!) therefore T&C's workmanship was sometimes a bit slipshod. Nearly all the parts are marked "Burmos" England. Steve.
