I am ill at finding out through a move I have lost 3 burners to a minature antique wood stove. I believe it was like a salesmans sample. My mother gave it to me from her and my fathers collection of antiques. They are round discs approx. 2 1/8" diam. and have a small square hole in it. If anyone knows of anywhere I could inquire to get replacements I would greatly appreciate the advise!
