Drawing of a 18-, 12- and 6-pounder

Title Leupe: Afteekening van een yzer Canon, van Metale 18, 12 en 6 pond, op de Fortres Nieuw Amsterdam.

These 18-, 12

and 6-pounders are designed for the fort of Nieuw-Amsterdam. The sub-Lieutenant Joseph Tilhenn of the artillery drew the design and considering nearly all his maps date between 1791 and 1795, these profiles and views probably derive from the 1790s too. The bores, rings, and knobs correspond to the late eighteenth century standards.

Scale-bar of 6 Rhineland feet = 21 'strepen'.
