Gabriel Riddle slider pencil. It is in excellent condition, no damage; imprint is crisp and clear; onion dome top; there are four inner chambers to hold spare lead. In December, 1836, Mordan and Riddle dissolved their partnership and in March, 1837, Riddle posted notice in “The Register of Engravings” that his pencil cases would be stamped “Patent G. Riddle Maker London”. This dates this pencil as one of his early ones, when he first started his own business. Later ones were stamped “Patent G. Riddle London”.
