I have 2 charcoal carriage heaters made by the Clarke Company NO.5B They were my grandfather's and I have had them for more than 50 years. I would like to know more about them. I used to have a box of long charcoal bricks that went in them, but that has gotten lost while moving around. I would love to know more if you have found out anything else in the past 2 years. I live in Springfield, Oregon, but my grandfather was from Stevensville, Montana and died in 1942. I hope to hear from you. Leona Clatworthy
