Have no cockpit in B22 , A6M2 , Spitfire or F4 I'm on update 6 of MSFS2020. Other than that you can fly them from outside but no HUD there
I could also make you a small donation if you can create for FS2020 the B17 and the other aircraft of the site: https://modshost.net/mfs2020/aircrafts/aeri-seconda-guerra-mondiale/
