A FINE PORTABLE WRITING SLOPE WITH WATT-PATENT DOCUMENT COPYING ACCESSORY, C.1815
constructed in brass-bound mahogany with tooled leather writing slope, the reverse with paper stowage tray and winding arbor operating brass rollers and baize-covered press, the lid with inset plate engraved with coat of arms and motto Virtue Parta Tuemini ['defend what is acquired by valor'] and initials 'EHH' -- 9 x 20 x 11½in. (23 x 51 x 29cm.)
Invented and developed by James Watt to save time in copying incessant correspondence between himself and Matthew Boulton, the system works by using special ink and semi-translucent paper. When pressed through the rollers, a copy is made which is read through the reverse. Carl Philipp Moritz describes seeing one of these in operation in his 'Travels', 1782. This lot is an elegant example of the earlier prototypes.
