House Gothic Condensed Bold has an S like that, but the R doesn't match.

Seems like a Red Rooster font looks like that too. Be right back.

Nope, not Red Rooster. It was House Gothic, but it was in the old version, not the current House Gothic 23.

I don't think that old version is sold any more.

Thank you, Mr. Yanega. Up to this point, I hadn't located ANY font with an S of that particular shape after having gone through thousands. Even though the R is different, it'll do.
