I believe it was the BH at the Cowan's auction. Sold for $22,800. My BHE 12 ga is a twin in terms of engraving---beautiful gun. Another 12ga with the same engraving was displayed at the Southern this weekend. I thought the engraving on my BHE was unique but I have observed a number of B's in the 1904-5 period with the same layout.
