Eric, the Tamiya Razorback is in my top three of the best model kits ever made. As a matter of fact, I’m considering building another one soon. Anyways, I’m no expert, but I know C and early D Jugs started out OD over NG in Europe but this changed as the war progressed. Some FGs, such as the 56th, used RAF stock to camo their Jugs in the field. Towards D-day and beyond, most USAAC fighters were natural metal, but of course there were exceptions. I would suggest finding yourself a set of decals for a Jug that flew on D-day and go from there. Most decal makers are good with color call outs on their particular subject. Ebay is a great place to find P-47 decals. Also, tape off and paint in your D-day stripes in lieu of using the decals. You’ll thank me later…
Its not exctly a website, but here’s my build of the Tamiya Razorback from last year.
