P-51B gunsight

[gary]

Can anyone advise as to the make and model of gunsights that were standard equipment in the P-51B aircraft or where one might find such information.
Any help is appreciated.
Cheers

According to Bud Anderson, they used the N-3 or N-9 non-computing reflector gunsights in the P-51B.

Not sure of the make. I imagine there were several manufacturers, like most other gunsights, building to designs by a main contractor.
