Identify aircraft part (2 Viewers)

[RichardSuhkoi]

This assembly has several markings; B73463 SA R2 C73350 a circular inspection stamp "AGWH 109" .
It seems to have a cocking feature and a trigger. Might it be a cartridge start device or flare launch device?
Does anyone recognize the numbers? British? American?
Google finds nothing. Very curious.

Hand control for a turret?

Hand control for a turret?

I see. Maybe like a tele flex cable release ? That would explain the bearing to allow articulation as the turret position changed?
I will poke around to look at B-24, Heinkel turret photos.
Thank you
