P-47 just inside the cowling - what colour?

[nmayhew]

looking into a P-47 engine cowling from the front, what colour would the inside be?

 

Natural metal, yellow zinc chromate, interior green...?

[LSP_Ron]

I've always gone with yellow zinc chromate for everything less the cockpit

Gray on camouflaged aircraft:

 

 

Usually natural aluminum or the squadron color on NMF aircraft.

According to the Erection & Maintenance manual the cowlings (along with the firewall and cowl flaps) were left in anodized natural metal finish. Only the engine mounts were finished in yellow zinc chromate.

 

P-47 Erection & Maintenance Manual - T.O. 01-65BC-2

 

Section VI - Finishes 

 

b. ANODIC TREATMENT
(1) .... The anodizing produces a surface of aluminum hydroxide in the work. Aluminum hydroxide has good corrosion resistance and provides an excellent bond for paint. It is soft and easily scratched, therefore the surface is given a coat of primer immediately after anodizing...
...
(4) The following aluminum, aluminum-alloys and aluminum coated alloy parts shall be anodically treated. ...

(c ) All interior and exterior parts and surfaces except those fabricated from the following alloys 
and when used as exterior surface covering of fuselage, wings, control surfaces and cowling.
(d) Alclad 24ST
(e) Alclad 17ST
(f) 3S
