This is an amazing entry, my friend @dbutlr!
Chipping looks great from here.
Regarding the antenna mast, it is true that you can find both configurations. The masts and, moreover, the wire antennas were items that could have been installed or removed, sometimes without any kind of pattern, especially during those times. Having a pic of the particular plane at the particular time would have been, of course, a blessing.
Nevertheless, if the mast is shown in the final painting instructions of the specific scheme, I would use it.
Looking forward to your super build!
