Looking for spare part manual of Emerson turret as used in the B-24

[Kurtl]

Gentlemen, I am looking for something like a spare part manual for the AAF Type A-15 EMERSON 250CE-1 (used as NOSE TURRET in the B-24). Reason for this is that I would like to see each detail of it's armor and weaponry. Can anyone help me? Thanks in advance. Cheers, Kurtl
