Henry Pyefinch, optician, philosophical and mathematical instrument maker worked at the sign of the Golden Sun, Quadrant and Spectacles at 67 Cornhill, between 1773 and 1790. This adaptation of Cuff's model has the normal focusing arrangement, where the stage is moved towards the objective rather than the other way round (as with later microscopes), but here Pyefinch incorporated a joint near the base, so that the instrument could be tilted to the user's convenience. This idea was followed up by Jones' Most Improved model in the late 1790's.
