The Coleman Model 523 saw decades of service beginning in WWII as a cook stove and as an autoclave to sterilize medical and dental implements. It has twin roarer burners with primer cups and stainless steel wind screens. A wrench was secured on the inside of a post and under the top burner plate two steel capsules held sets of spare generators, valve packing and cleaning needles. In the center of the bracket between the two instruction plates is a very light strike of the Coleman logo, followed by Model 523. The pot supports, which also stabilize the stove, fold in to make a rather compact package.
