Richard Reeve, or Reeves, of Long Acre, was the foremost fashioner of optical instruments between 1641 and 1679, and "perspective-glass maker to the King". This term probably signified a pair of binoculars, though it could also mean a telescope (which Pepys called simply "a glass"), or even a microscope.
In August 1664 Pepys will indeed purchase a microscope from him, "the best he knows in England, and he makes the best in the world." 5 pounds 10 shillings is "a great price," but Reeve throws in a Scotoscope, "and a curious curiosity it is to [see] objects in a dark room with." (Can others elaborate?)
"Young" Reeve, in the entry of 23 March 1659/60, would be Richard's son John, who took over the family business in 1679 and ran it until c. 1710.
