Neat set up, and a fine show Jim. Thanks for sharing!
Tommy i think the valve is original from KMV?
At least these and the SS Chinese fish-tank valves are amongst his "extras".

Jim, there does seem to be an original deeper gelfuel burner available there as well 
Well I'll be. I like the options, going to have to look into these.
Sorry Jim, your post, great video.
