We're there not heavy fighter and bomber variations on both the A and the B model of the Me410? I was also surprised to see that it was entering service in 1943 rather than late 1944 as I had originally thought it might have. Amazing that it couldn't fit a pair of SC500s without the bomb bays being open... I guess that wasn't the original idea for the type? What about external stores or was it restricted/limited in doing that? Obviously internal carriage is better for aerodynamics.
All of this makes me really want to have it in the game someday (I mean fully... Don't get me started

). It seems like it would be very interesting to fly... With a Stuvi bombsight for dive bombing that would be idea as a tactical heavy fighter. Better than guessing with the Bf110G-2 which is often what I find myself doing online. I guess the other real draw would be bomber interception with all of the various armament configurations.
I saw drawings in one of the links for a dual MK103 install but I read somewhere that it was never used. What happened there?
