the 111P has a DB601 engine.
And yes, this overhead MG15 you can see from the bombardier position. But thats a BUG, because the ingame 111P is not armed with it.
and (note, i dont have the actual BETA) i hope 1C will remove the supercharger shifting 'bar' and levers in cockpit. They dont work in game, and thats ok, because the DB601 had a automatic supercharger...there was nothing to shift
