We do not know the model number (which was sandblasted then painted over) to our old Scandia/Franklin Cast cast-iron stove. It has double doors that open side to side with an easily removable panel (currently cast-iron) in the middle of each door held on by four bolts. We were wondering if we could replace them with glass. Each door has a vent under the panel with a sheet-metal spark-guard held by two bolts. We were wondering if we could make them into window vents or whatever those newer stoves with glass have to ceap them clean. (We are sheet-metal workers.) If anyone knows anything that might help us then please let us know.
