if i'm not mistaken, the bottom is the same font as top but a different weight. the most similar font i can find is the set of porsche-like "911" fonts from iconian. i've seen this image's font elsewhere in print as well, but i've forgotten where. this image was made from a photoshop custom shape vectorized from a scan of the actual logo. the R, G, S, and K seem to be the key letters for ID.
