rod spring
x1 Rod spring, B198369. Manual says free length 9-1/4" to 9-3/4", 209 to 297 lb at 6-1/8". We measured .70" O.D., to fit on .379 shaft and the existing spring 7.5" long.

Ring Sight on Pampanito. The rear sight, bar and socket are from the Army style sight and we think correct. The front sight and adjustment are from a Navy style 40mm Sight Mk 6, Mod 3 and do not belong in this configuration. They had a badly made adapter piece with lots of Bondo.
We need the x1 Army style rear site and x2 correct Army style front sites and mounting piece to fix the gun on the boat.
