Pictured below is the gunsight for a Ball Turret. It is a Sperry K4. It is HUGE! I haven't opened it up, but the only reason I can figure it is so big is that it has the stabilizing gyros built into the case, which is different from other WWII gun sights. Absolutely brand new, never used. I am looking for a Ball Turret to restore, or pieces, if you have any...
Last photo is of the truck it was sitting on, a 1942 Dodge WC53 Carryall.
by it's lines it looks very simular to standard top turret sight in most ww 2 aaf bombers, only yours is a size bigger. pretty neat, never saw a ball turret sight before. thanks, tom
