Claude Ledger jewel gauge hand-made antique watchmaker measuring instrument

Description

High quality jewel gauge hand-made by a single person - Claude D. Ledger - watchmaker who builded The Jessop's Clock in San Diego.
I reckon, he used this gauge for his own labour purposes and not for sale.

Huge solid gold chatons at backplate
Original leather carrying case
CONDITION:
Works but requires  basic adjusting
Sides of a leather carrying case are lousy
