Hello folks, I'm a newbee and have already found the forum very useful. I found my late father's stove in an old pigeon lost last week. Within a few days, I had gotten enough info to fire it up. I can't date it and have no idea the last time it was used but it lit with fuel at least 20yrs old, possibly twice that! What I would like to know (apart from it's age)is : Is the burner and spirit cup supposed to be black and how should I go about refurbishing the grate supports?
