Hi All, Evening Star for one. The Water Gauge mountings were 1/4"x 40 drilled and tapped into the backhead,the Blower cons were 3/8"x 40 and when Martin Evans took up the design he drilled and tapped 8BA screws into the Boiler shell to hold the top feeds. This all happened somewhere in the late Sixties. Regards Clif ----- Original Message ----- From: "R.L.
