I was asked to make a gunsight available for the B-25H with range markers for the 75mm cannon. The sight I created is from the 250IAS test data for 75mm round IP.
You will need to push your head position up until the number 5 just shows. Also, you will have to practice to get the range markers to work. In real life several things were against accurate aiming. Your speed and your angle of attack. For example, pointing your nose down at 2k your 2k shot will be short. And at 4k and 5k, lifting the nose to put the pipper on your target can end up with a 6k shot. I found in testing on a gunnery range offline, 4k shots I was about 5k from the target and 5k shot about 5.5k. You will have to practice.
I found a photo showing the reticle plate for the Italian Type A gunsight reticle, so here is a white and a red version just because red works better in AH3. I made a red dot just because. And updated the wirbel and osti reticles to red because it's easier to see on the fly.
You can unzip these files directly to your sights folder. Hang on to the zip file since I doubt these files will be added to the AH3 install.

Italian Type A white and red reticle.
Red dot, move the alpha slider all the way to the right and it will glow in daylight.
