Info

Depth Gauge in inches. Maximum depth measuring is 6 inches. The ruler is made of steel, the slider is brass.

(a) Not clear if the inscription "LACY" is the maker, or has been the owner of the tool. Presume the latter as the letters seem stamped manually.

From seeing likewise gauges, it could have been made by Holtzapffel & Co from London, but as there are no other marks, not sure at all.

Inscriptions on the slider:

E. LACY

Inscriptions on the rule:

LONDON
