I recently aquired a beautiful National FBXA with homebrew preselector and noticed that 'K6BV 1935-1953' was inscribed inside on the top of the aluminum Det can. 'W3EXI' was inscribed on top of the Osc can. OOTC lists K6BV as Forrest Barr, now SK. Did anyone know this gentleman? Anything you can tell me about him? thanks, Doc K7SO
