The L-5 maintenance manual specifies, ” Visible portions of the cockpit shall be coated with a finish having a yellow-green color. This yellow-green primer shall be prepared as follows:
- Zinc Chromate Primer (AN-TT-P-656) 1.0 Gallon
- Enamel, black (SpecificationAN-E-3) 0.1 Gallon
- Toluene Substitute AN-T-8 1.0 Gallon”
Whats the modern equivalent to achieve an accurate color with a good corrosion protective coating?

Bill,
I”ll have to dig for that but Mike Kennedy has been doing a really nice interior restoration and has it pretty much nailed. He has sent a bunch of pics and a write-up that I need to post here for the benefit of everyone who doesn’t have the time or resources to strip the fabric and start from scratch. Here’s one of his pics. Standby and I’ll try to get the other info posted by tomorrow night.

p.s. There wasn’t a single finish color except perhaps in the cases of aircraft that came out of major overhaul. Stinson used multiple sub-contractors and they all had different versions of interior green top coat and yellow-green [actually black-green] and yellow primers. Some mixed them in-house and some bought them pre-mixed. Depending on the substrate, the primer, the thickness of primer, and the topcoat, if any, there was a virtual rainbow of greens in an L-5.
The Marine Corps also had their own variations as we’ve seen and several surviving OY’s that went through Cherry Point. so, it depends if you want to try and depict that or a factory-fresh look. For example, I have a pile of spare unadulterated-by-civilians window frames and there are at least two distinct factory greens and the Cherry Point green, and one other I haven’t identified. I took a bunch of pics showing this but they’re still on my phone. I’ll post them once they’re downloaded.
Duncan cameron, Bill Tromblay and others have put a lot of effort into discovering and duplicating the Navy / USMC / USCG way of doing things, so hopefully they will be prompted to chime in here.

Hi Bill,
Remember that section of the manual is “finishing Specifications” and is for work in the ‘Field”. That is not necessarily what the factory supplied… i use a product by Alliance Coatings in El Cajon , CA. the WWII Green primer is their MIL-PRF 85285 Lusterless ( flat) <span style=”text-decoration: underline;”> Primer Green</span>. In the past ,we had a custom color match made off of many good Original primer samples. This product is super close!! It is the green which is seen in many WWII aircraft. The “yellow” zinc chromate or “yellow” primer is called “<span style=”text-decoration: underline;”>Zinc Green</span>” and is almost the yellow in color.
You are looking for the “Primer Green” color for the interior tubing.
The paint is actually a top coat color and will need a good primer installed on the metal first. It is almost impossible to find that color in an actual primer anymore.
It is expensive and a 2 part paint. It takes 2 days to dry properly , but it is consistent in it’s color and level of gloss (flat). It is the best I have used.

Here is the June 1943 Color Plate for Interior Green. A friend of mine graciously lent me his color plate books. While colors on screens may vary, it will provide a fairly close approximation to what you are trying to achieve. I took this photo under LED light. As was previously mentioned, the factory and various sub-contractors had variations of this color. It was a Flat/Matte finish.
