A FINELY MADE WOODEN MODEL FOR AN EARLY TWO-BLADED RETRACTABLE PROPELLER, CIRCA 1855
the blades with truncated tips bolted to boss with brass bolts, loosely fitted shaft and carved end bolt, mounted on plush base with dome cover, the propeller -- 8in. (20cm.) diameter

In the early days of propeller development, founders had trouble casting them in one piece and it was common to case the blades and bosses separately and bolt them together. The unusual truncated tip on this model suggest that it was designed to retract when the vessel was under sail, a feature that remained almost until the end of the sailing navy in the 1870s.
