One more view that hopefully looks more full-scale. And, for anyone in the future using this thread for research- 5 1/8th inches gave me pretty much exactly 35 triangles on a 16' 1934 HW. Also, it took four coats of the red and blue on the triangles to fully cover the gloss white. It's a lot of work. Don't start this if you're not ready to spend hours and hours taping and painting.
