That’s pretty.
We also have a functioning Glenwood Gold Medal combo wood/coal/gas stove in our kitchen.
It has four gas burners, four wood burner plates over the fire chamber, a lower wood fired oven and two upper gas fired ovens (a broiler on the right and a thermostat controlled oven on the left). The thermostat is a Robertshaw Automaticook - completely mechanical. It has a carbon rod inside an adjustable steel tube, so as the oven heats and cools, the tube lengthens and shortens relative to the carbon rod, closing or pushing open a spring-loaded gas valve.
I love these old things.
