Keith O'LearyPatrick, I've collected the S74 white silks with backs for 10 or so years. I know they are mentioned in Lipset's book, but I've never seen a Helmar back. I've owned 6 or 7 of the Red Sun backs, and see them infrequently. I've had other S74 collectors ask me about the Helmar backs also, they've had the same experience. As a side note, the Turkey Red blue back variation is another hard one to find. Keith
