Minin Honest John Build Part 15 Scale Factor for Masking

The real M-50 Honest John diameter is 23".
The model diameter is a BT-50 at .976"

23" divided by .976" = a scaling factor of 23.56

All the measurements on the Peter Alway drawings will be divided by the scaling factor of 23.56

Instead of painting the model an overall Olive Drab, I decided to paint it in the test round pattern shown in the lower right of the Alway drawing.

The tip of the real HoJo is light grey down to 32.41".
Divide 32.41" by the scaling factor of 23.56 and the grey on the model will go to
1.37" down from the tip.

I divided the scaling factor into the other nose cone masks and came up with the measurements shown in the picture.
