WoW!!
The company who reconditioned this P51B got the gunsight correct. The vast majority of P47\51b,c that were shipped to England had their N3 gunsights pulled out and replaced with Barr&Stroud MKII at the staging locations where they were made ready for the ETO or MTO. No P51b\c ever had an N9 mounted from the factory like ours in AH2. The first P51d shipments to England did have the N9 mounted from the factory. So our P51b has been field modded with more than a Malcom hood.
Waffle waaaaaaaaaaaaaaaaaaaaa!!!!!!!
