Hello I have a Radius (LTD.) 43 with a silent burner here. It has been repaired and air restrictor tubes have been made for it in order burn different types if fuel. This is a wonderful little camping stove. I would like to purchase a new outer flame cap for it and I am having difficulty trying to obtain a suitable Optimus or Primus part number for what I am looking for. I've come up with Radius part number 112/33 for the 43E stove and Radius part number 43/33B for the Radius 43B stove. The stove I have has no suffix at the end. It is labeled Radius 43. Is there a compatible silent burner cap that was/is made by any of the stove companies? If any measurements, hole counting, etc... would help, please let me know. Thank you.
