| Description | Mints and Mint Engines (14 items).
20 horse power crank engine, with 23¾ inch cylinder, 5 foot stroke, parallel motion, cast iron beam, cast iron connecting rod.
Reverse general view of the engine, plan of the engine and boiler; reverse plan and sections of the engine and boiler houses; sketch plan of the engine and tilt hammer, Sep. 1804, marked "Phillpot's shaft, Navy fly wheel - this plan to be adopted"; small plan of the engine and tilt hammer - direct and reverse copies (the direct copy is marked "Sent to Mr. Warberg 10 Jan. 1805"; 2 small rough pencil sketch plans of engines; 2 rough plans of part of the premises; plan of the premises showing the forge and the bellows engine.
Also plan of the premises marked "Danish Mint copied from drawing brought by Mr. O. Warberg 11 Jan. 1805" (this drawing appears to show the forge; part of the building is virtually identical to that depicted in the plan showing the 2 engines, and it appears to depict smiths' hearths and bellows rather than mint machinery).
