Some users had unnaturally large amounts of time in their hands. Here, the handles are both ebony, held in place with tiny brass nuts that have infinitesimal spanner holes rather than the usual flats. This drill came from a famous on-line auction with a Jacobs chuck which decoyed most bidders into thinking it was a junky modern drill. The stalk on which the mushroom-shaped breast plate is mounted is a casting with a cruciform cross section. The crank arm was turned between centers and then bent to its present shape. The main gear is a casting which has been machined all over. The spindle has a Morse No.0 (?) internal taper, a size for which I have as yet found no taper-shank drills to fit.
