A precursor to WW2 turrets, this early 1930s B-10 nose
turret looks like something from a Jules Verne novel.
Also listed in the tail turret section, I begin with the SAC 7 tail turret
here as it was the first turret used in the front of a B-24 when a resourceful
repair depot in the European Theater replaced the original B-24 D's "greenhouse"
forward gun position with the Consolidated Vultee tail turret, and thereafter
the Oklahoma City Modification Center began installing the turrets stateside
before shipping to the ETO. Eventually all Liberators were manufactured with
nose turrets.

continued to use their Sac 7 for the nose position turret, but the Emerson nose
turret (AAF #A-15/Navy #250CE-1) replaced the Sac 7 tail turret as the B-24
forward gun turret on planes manufactured at the Ford Willow Run plant in Michigan.
The Emerson turret was somewhat of an improvement aerodynamically, but still
had the aerodynamics of a bus. It had a wider field of fire but as with other
nose turrets of the time, it did not have an air tight fit with the nose section
and as a result leaked a tremendous amount of air into the fuselage. At 25,000
feet over Germany this air could be as cold as 50F degrees below zero.
