Some progress on props, although I ran out of the wood I was using and spent part of yesterday pawing through the billets I inherited from a wood-turner friend some years back. I'd thought the stuff I was using was Honduran mahogany, which I have about twelve pounds of, but then realized it was nothing of the kind... it might be quarter-sawn cherry, or Swiss pear. I found some straight-sawn cherry that should serve, though. The battle continues.
RE: the colors:
- Big Sky, thanks for bringing that photo up! I had seen it, and studied it closely. The original was found by Marc Chassard in 1999, and shows Jean Chaput's machine 940 of Esc. N.57. But in a lot of ways it raises more questions than it answers... and so we fall down the rabbit hole of the Great Nieuport Camo Debate :-) The problem with most of the versions on the web is that they seem to have been zapped in Photoshop with the "Saturation" tool. As near as I can figure out the original autochrome was much less colorful, as in this copy from Albin Denis's monumental Escadrille site:

Marc Chassard, who was also a co-author of a book on early Nieuport doping schemes, decided after much study that that red-brown on the front of the machine was in fact simply the varnished "cheeks", the side pieces made up of diagonal laminations of mahogany veneer. And it does seem a suspiciously close color match, as seen in this photo of the Belgian N.17 undergoing restoration:

This whole question was addressed by Xan in a wonderful post titled "Camouflage Francais Deux Tons (3? 4?)" on the French 1914.forumactif.com forum back in 2018, where he laid out his reasons for going with a simple two-tone green/brown scheme. But there are valid reasons for going with three, or even four, as others have pointed out (including Andreas, replying on the same forum).
I know I'm probably re-hashing stuff that a lot of you are already familiar with (and are probably sick of reading!) but I'm trying to document my reasoning for the choices I'm making as I go along.
- Uncle, likewise thanks! I wasn't aware of the plug-in, I'll do a search for it. I'm altogether too prone to trying to re-invent the wheel.
- Rick, I had a lot of respect for Dan-San, but he sure did have his opinions! I had an exchange with Ray Rimmell a couple of years ago where he referred to his arguments with DSA with some humor, and obvious fondness in spite of the latter's curmudgeonly ways.
- Andreas, I especially liked your comment to Xan on the 1914 forum RE: the argument that the photo of the Nieuport factory only showed two spray-guns, therefore only two colors. And your 3-color Special Hobby N.11 was a work of art, and I'm seriously considering using it as inspiration for this project.
Thanks all, and sorry if I'm rambling!
