As luck would have it, I managed to re-find the site with ease:
If you read it all, you find the specified color was "Gray Number 123," and that came from Army paint color specification No. 3-1.
Further reading tonight led me in another direction... Seems that what modern Jeep restorers prefer to use is FS 36173, and a common paint supplier mentioned is Gillespie.
This company in the link below supplies parts to restorers. "36173 Lusterless Navy Gray" :
Also read a discussion forum somewhere in tonight's travels claiming closest you will find in model paints will be FS 36176. No idea how true that is, but worth mention I think.
Another forum of restorers discussing the subject claims that all Jeeps leaving the factory were in either Olive Drab or Marine Corps Forest Green. All Navy Jeeps then painted gray were done in the field...none are known to have come off the assembly line in this color. So, it recommends first painting the vehicle in either OD or Forest Green, then overspraying with the Navy Gray, and leaving areas (like under the hood, etc.) that could not be reached by a spray gun in the base color. Again, no idea how true this is...got it from a discussion forum of folks who restore military vehicles.
Hope this gets you started. Looking at all the windows I currently have open, I think I could read on this subject for the rest of my life. I've given you the highlights. You are welcome to double check me and explore further.
