Can anybody help to identify this part found in southern Germany. Caliber 50 cartridges were found nearby.

I am a bit surprised to see castle nuts with cotter pins rather than safety wire.
It's pretty typical for an all moving assembly. I don't think I've seen safety wire or cable to prevent rotation on a moving joint in my entire career
 
Of the two inspection stamps
The first I do not recognise
The second is a Heat Treat stamp indicating the part was made from annealed alloy then heat treated for strength.
 
Republic Aviation had 2 plants - the first one at Farmingdale NY, and a later second one at Evansville IN. The Farmingdale plant used an RE, while the Evansville plant used RA.

EDIT! Changed "The Farmingdale plant used an R, while the Evansville plant used RE." to "The Farmingdale plant used an RE, while the Evansville plant used RA."

Thanks for the correction. He who never made a mistake never made anything and correcting data when you made a mistake is true honesty.
