Agree that wooden PB's were earlier than brass, and that they existed on the guns, but within the Bethlehem / Lehigh school, the comb nose was generally straighter (Peter Neidhart for instance) and general profile more robust on guns with wooden PB's. The subject gun here has more of a Roman nose to it, which is a more prominent feature that developed somewhat later, closer in styling to Jacob Kuntz, Stophel Long, and to a lesser extent, John Young than it is the earlier work of Neidhart and Rupp. The style sort of evolved and merged in to the Philadelphia school later on. My reference source for the observations is the KRA # 10 disc, and many conversations with Erich von Aschwege.
