Parker Liquid Lead Pencils continue to fascinate us. Here is a slender model with an almost Parker 21 like pocket clip from the 1950s. Sadly, the idea of a liquid lead pencil never really took off, but we still have some handsome examples of them around. This model shows more moderate to heavy wear from use but a rarer imprint than many of these pencils we've seen. You can also see a little rust no the tail cap. Unfortunately, this pencil's refill has run dry, and they don't make these refills any longer. 13.1cm.
