The B&W 350/2Q4 shows up fairly frequently on the bay.  I'd say that the EWL rig could be duplicated today. 
I wish I had never sold the one I built back in 1962 and the VOX box I built on a 5x7x3 Bud chassis. I don't remember if I sold it in Sacramento before I left Mather AFB or in Ft Worth after I got to Carswell AFB in 1963.
