You could help collectors by naming the dealer.
Hi Dave,
Sorry - just got back from SOS noticed your question. It was an older gent at the the Allentown show named Rodney Brown. He has a museum in New York
www.thewarmuseum.com He said that the Dagger Pictured above was featured in a Time Life book series and came from a collection of a partner of his that he bought out.
He seemed like more of a history buff and not so much a collector of edged weapons in talking to him.
Hope that helps,
Scott
