An article on pages 111-125 in Volume 33 No. 4 of "Arms Collecting" discusses the English gunner's caliper by David S. Weaver. The article identifies this example as the third standard form which dates between 1760 and 1830. As with earlier forms, this is a 6" inside/outside caliper with scales for diameter of shot and bores of guns identified by the weight of shot fired, with additional scales for angles and degrees and diameters in inches. There are tables for weight of powder for proof and service of iron and brass guns as well. However, this form has the added table "quantity of powder for filling the chambers of brass mortars & howitzers" which are identified for sea and land use. The table for brass guns is expanded to include light, medium, and heavy cannon. The third standard form was a more utilitarian instrument and was made of thicker brass sheet. This form is hand engraved and was made by many of the leading instrument makers of the period and is the form most frequently found today. This example is inscribed "Dollond London". Dolland was a prominent maker of telescopes and other instruments. It is known that George Washington had a telescope made by Dollond of London. The caliper tips had small dovetailed pieces of iron to prevent wear, which are now absent. CONDITION: Very good with all inscribed tables and markings remaining crisp. A few scattered marks from use and retaining a polished surface. A very scarce military instrument by a superior maker.
