Can anyone provide a clear scan or photograph so that I can recrate this for my model? This was the type used in the original 1960’s edition, red, with a running horse in black and white, with “P-51 Mustang” in white (as I recall).
Here is an inage of the completed kit:

Thanks!
This is from a 1961 decal sheet. As you can see the decal is in black, white, and clear colors. I believe the red was the native color of the stand. I have the 1961 issue stand and the recent Revell Germany reissue stand and both are in red plastic.

I also thank you !
I bought one of “Horseless” kits from Hobby Lobby.
Way cool! 2 years older than I am!
Will clean this up and repost a version suitable for use with a decal kit!
BIG Thanks!

Note it’s also USAAF, for the WWII generation! 
Finally, my images from the “Gathering of Mustangs” in Ohio in 2007:
