The mechanical pencil was first invented in Britain in 1822 by Sampson Mordan[1] and Gabriel Riddle. Earliest Mordan pencils are thus hallmarked SMGR. Sampson Mordan continued manufacturing pencils and a wide range of silver objects until the second world war when their factory was bombed.

The first propelling pencil was patented by Sampson Mordan in 1822 and the first hallmark SM appears in 1823.
There was a 1824 SM hallmark but Mordan went into partnership with Gabriel Riddle during 1824 and the hallmark SM GR appears. Riddle was a stationer.
