One treasure was a complete set of Cross and Cockade Journals in their original envelopes. It was published quarterly by the Society of World War I Aero Historians form 1960 to 1985. The magazines were filled with pictures and research people had done on WWI aviation. One piece of research was "Project Butterfly" by Allan Toelle, et al. They had researched French camouflage colors including the pigments and formulas to make the colors. They also had figured out the paint scheme used by each subcontractor which built SPADs. SPAD or the Société Pour L'Aviation et ses Dérivés, which roughly translates to Society For The Aviation and its Derivatives, built 2 of the great fighter planes of WWI. Along with the Fokker DVII and the SE-5a, the SPAD VII and SPAD X111 were state of the art in the later part of the war.
The goal was to make the Fly Baby to look like it had been sent to one of the SPAD subcontractors to be painted. I selected Avionnerie Kellner Frères (Airplane Builder Kellner Brothers) as the painters for my plane. Kellner was a famous coach builder for luxury car makers of the period. They had become plane builders to help SPAD with the war time problem of more orders than they could build. Keep in mind that able bodied young men went off to be slaughtered in the trenches and the old and women new to the work force did all this work. The first airplane they probably ever saw was on their first day of work. They were not building museum pieces nor the high quality coaches for which Kellner is still famous.
I chose the markings of the 103rd Aero Squadron of the 3rd Pursuit Group, 1st Pursuit Wing, 1st Army, American Expeditionary Forces. They were the successor to the Lafayette Escadrille which meant they got to have the coolest Indian Head insignia of the 4 squadrons in the group. Based on the order issued 27 August 1918 they had the Green (3) and Red (2) stripes on the upper and lower wings, as well Yellow and Black airplane identifier numerals on the fuselage. I've chosen the Red nose of the 1st Flight aircraft. The Indian Head used during this period was vary consistent which would imply they had a pounce pattern they used to layout the insignia on the fuselage for the sign painter to follow.
Unfortunately when I tried mixing colors based on the formulas in the "Butterfly Project" they all came out wrong. I can only assume they did not measure their pigments with enough precision, I'll never know. As a result I took their information and built an Excel spread sheet to calculate the formula for each color. I them made samples and took them around to various museums during my business travels until I had formulas which consistently matched old fabric. I also bought color standards (8" x 10" sheets) from Munsell to match or bracket the colors they found when they measured old fabric. My samples included pieces of the Munsell sheets and actual dope samples from my last mix.
The pigments were mixed with a mortar and pestle. The colors don't look correct at all until you add the aluminum powder to the dope mix.
I now have an Excel spread sheet which allows me to calculate any quantity of dope. I also have extra pieces of the Munsell sheets and a 30 gallon drum of aluminum powder. Today dope makers sell the aluminum as paste so there was no easy way to figure out how much to use to get the correct colors.
If you need help with French Camo. I can help, send me a note.
At first some of the colors were way off from the old fabric. By taking pictures and making notes I quickly got to where the colors matched. Then it was a process of finding more places to visit to check the colors against more samples.
I don't know if the American units repainted the National markings so I assumed they were painted on at the French factories using their colors. The wing at the right is on a Caudron at the Air and Space Museum, everything is factory original. The sample below seems to agree with my factory paint theory since the cockade it was cut from is clearly the American order of the colors using French dope colors.
Here is a sampler of the colors doped on Grade A cotton fabric. With all this information it's time to start painting.
