This image shows the P-38 gun bay minus the 20mm cannon. Quite a bit more space when you get all that hardware out of the way.
Also I believe that slot in the middle is the 20mm cannon ejection chute were the shells are stored in a chamber. It looks like that is where the cannon belt feed magazine is attached above that chamber.
20mm Magazine being loaded.
Drawing of lay out of 20mm cannon.
Good image of the magazine as well as the top of the shell catching chamber.
It also aligns with the 20mm shell ejection door.
Door better seen in these two WWII historically correct period photos.
Another image of a different armed droop snoot.
I wonder if these armed droop snoots were common? After all they were not done at the factory
If only there was some information confirming this.
OH MY.
Goodness this book preview confirmed they did do this for the benefit of the crew. Now we have a guy laying down in the nose with two machine guns as well as ammo trays had to be tight but they clearly fitted them all in.
If only there was a reference about armed Foto recon aircraft.
Sadly no complete access to those pages but they do give a brief glimpse.
TAH-DAH.
Book is on the way.
