If any would have the very latest, it would be a high end English maker's factory. Extrapolating from that, a drill press at a high end English gun factory, to consider that John Bonewitz or Frederick Sell had one, would be a stretch. I've read a number of gunshop inventories from wills and the Moravian archives at Christians Spring over the years and don't recall a drill press described. Boring and rifling machines, yes.
