Keep in mind, that white guards were priimarily used on Custom Colors back then. Stnadard finish would have had a tortoise guard.... soooo Custom Color Early Transitional Jazz ?? Even in this very down market, you're looking at $6000+ actual selling price on the very low end. I'd say that's a pretty conservative number. Possible up to $10,000 to the right person on the right day depending on condition , case , covers , etc.
