Frank,
Note that you have described only one repop Signal sign. These signs have been manufactured by several companies with differing characteristics. Check out the attached photos of another repop Signal sign, 11 3/4" diameter, red band on the edge and gray back. The common traits for all Signal repops is no white band on the edge and the mounting holes are closer to the edge than the genuine signs.
