Here are some SBD on aft deck of USS Randolph

And now excuse my extremely crappy montage, I had to do this on the fly with irfanview, don't have gimp installed at the moment:

You see they fit about the same way as the real ones
Also, take your time and measure B-25 wingspan & carrier waterline beam on my first picture. You will find they have the same ratio as you would expect from RL numbers (28 to 20m)
