P-47M P-47N questions

[Thunderbolt19]

Hello everyone. I am currently researching the P-47M and N and have a couple of questions.

1. Was the P-47M equipped with the K-14 or MK8 gunsight

2. Was the P-47N equipped with the dive recovery brakes

1: The P-47M was equipped the K-14 gunsight

2: The N did not have dive recovery brakes.
