This single burner Waterman “Giant” counter top model turned up on eBay this week.
As you can see from the photos, the burner is divided into two parts for low and high heat. The gas apertures are right next to the stop cocks – gas technicians can adjust the diameter for either LP or natural gas.
If you ever used one of these back in the day, as in more than 50 years ago, I would be curious to hear from you as to how you used it. Summer outdoor cooking? Accessory burner in the kitchen? When camping?
