Here is a good used working Optimus 8R White Gasoline Sweden made vintage single burner backpacking & camping cook stove.  Stove has been cleaned, stove case has been repainted and in excellent ready-to-go condition.  Has been tested as seen in the last photo.  Very light weight & compact for easy pack carry.  Measures 5" in width, 3" in height and a dry weight of 1 lb. 7.9 ozs.  The included flame adjusting key is also a field repair tool for this fine working stove.
