Description:

Brass and Steel Depthing Tool, William Illingworth, England, late 19th/early 20th century, the brass body marked Wm. ILLINGWORTH MAKER, with steel runners and gnurled thumbscrew tighteners, lg. 13 3/4 in.

Note: Though generally used to determine correct engagement of wheels with pinions, depthing tools, we are told in Crom #2, were versatile and adaptable to a variety of watch and clockmaking uses (pp. 414-422). Depthing tools are found in trade catalogues as early as Jacob Leupold's (1724) (Crom #2, figure 70), and appear relatively unchanged in form since Berthoud's catalogue (1773) (Crom #2, figure 154).
Estimate $1,000-1,200
