I just had to share this link I found earlier, it's supposedly the only known film of the INAEC Sikorsky S-43 NPC-31 operating in the Philippines around the mid-1930s.

Originally from criticalpast.com this is even more rare given that it's in color, not colorized. I've tried to get Bruno Vanhecke interested in doing this particular recolor for his S-43 model.
Anyway, I've grabbed as many screen shots as possible so I can do an authentic recolor given the chance, also to archive photos in case the video gets taken down.
