Mordan Hallmarks

A chronological list of hallmarks (maker’s marks) used by S. Mordan & Co., as provided on page 203 of The KB Collection of Pencils (the link to a viewable version of the complete book can be found in first section above). Note that there is at least one Mordan mark missing from this list  that we know of – “S. MORDAN & CO. PATENTEES”. Based upon the design and construction of existing examples, it seems likely that these date roughly around 1839-1842.

William Riddle letter published in "The Builder" - 1861

This letter was written by William Riddle and published in the August 3, 1861 edition of “The Builder”. It is interesting in that it provides additional detail/context of the Sampson Mordan/Gabriel Riddle relationship as well as some insight into William Brockedon’s efforts to use compression of waste material from the Cumberland graphite mines to create new “leads”.

My Wish List

Rare is the collector whose collection is ever “complete”!  I’m always keeping an eye out for items of interest and the following is a list of some of the items that I am keenly on the lookout for … Let me know if you have items that you wish to part with or are aware of someone that might…


  • Mordan
    1824 & earlier Mordan Riddle pencils, as well as1832,33,34,36.
  • Commemoratives
    Pencils commemorating Victoria and Alberts Wedding, Wellington, or events such as Exhibitions, deaths of major figures, etc.
  • War Related
    I have several war related pencils (Khartoum, South African, First World War, and I’m interested in mechanical pencils made from battlefield relics (bullets) and trench art in the form of inkells, etc.
  • World War Two Escape Pencil
    An original World War Two escape pencil with silk map would be amazing. However, I have yet to come across one in the wild.
  • Figural Pencils
    19th century figural or novely pencils are of interest
  • Stanhope Pencils
    Most of the stanhopes that I have are late 19th century souvenirs and pertain to views of towns/villages in the U.K. I’d like to find a 19th century “peeper” or stanhopes with subject matter other than buildings or religious sayings.
  • Hard Rubber Pencils & Dip Pens (Non-Black)
    The Goodyear and A.G. Days hard rubber compounds were used by many different American makers. The majority of those that have survived are black hard rubber, although I do have a couple in “red” and I’ve seen am image of one in blue.
  • Multi-Function Pencils
    Early Makers such as Sheldon and Dawson made clever combination items in the mid-1800’s. Acquiring a Sheldon Escritoir would be a highlight.
  • Early American Makers
    e.g. Hague, Addison, Lownds
  • Early British
    Pemberton, Wilmore, etc,

Inkwells & Miscellaneous

  • Mordan (Sampson) Inkwells
    of any sort
  • Mordan (Francis) Inkwells, Ink bottles, or writing implements
  • Travel Inkwells
    Figural or unique in some fashion
  • Snail Inkwells
    or Encrier Escargot; double or triple; or rare design / patterns
  • Pen Nib Boxes
    Interesting boxes that still contain at least some of the original contents
