Lovely screenshots, Jan Kees!
Following the release of the P-39 this summer, a blue-print accurate B-25J (specifically the B-25J variant, not the earlier versions) is in our plans to enter development with a projected 2016 release date. I got quite a bit of B-25 research in throughout the year last year, visiting various locales, including the world's leading B-25 restoration company and a few other operators:

The local B-25 operators ground school is coming up next weekend, where I'll be sure to be taking notes.
Speaking of the RCS model, the most recent versions are from when the model was rebuilt/modified to resemble the restored CAF B-25J "Yellow Rose", which besides having the post-war modifications to the carburetor/scoop and exhaust, the top turret is also not authentic to what was originally fitted to B-25's while in military service, it being a Martin turret. The Martin turret is what many of the restored B-25's flying today have, not only because they are more plentiful, but that they are also fitted without having the full 'post' that extends to the floor, as the original B-25 Bendix turrets have, providing more room for riders. Unfortunately, though, when a Martin turret is fitted, the top structure of the fuselage takes the full weight of the turret, which it was never designed for, since the original Bendix turret spreads the weight into the floor mount as well, and on those fitted with Martin turrets you can often see the skins around the turret to be wrinkled/buckled a bit, due to the extra strain placed on them. My local B-25J, "Miss Mitchell", was the first restored B-25 to have an original functioning Bendix top turret (as early as '93) - with a number of "claimed kills" in the years since - and it also has a functioning tail turret and fully-functioning bomb sight and bomb control panel, with all of the arming/release mechanisms wired up and working (unfortunately I didn't have my phone/camera on me the last time I was up inside the cockpit of "Miss Mitchell", otherwise I would have shared a few photos of it as well).
