Eberhard Faber Blu-Blak Ink Pencil 740 Medium
Blu-Blak pencils were made in both medium and hard degrees. In Canada, they had a brass end cap. "Ink pencils" are similar to copying pencils in manufacture, both containing lead mixed with a dye. Once improved copying methods were invented, some copying pencils were used more as an indelible pencils much like a ball point pen would be later used.

Eberhard Faber Hektograph Potent Copying 754
I'm not sure what makes this copying pencil "hektograph". Most modern hectograph pencils seemed to be used to transfer stencils from paper onto skin for tattoos. These pencils came with a brass point protector. Check out this site for more.

The Microtomic drawing pencil line was made in 18 degrees, from 7B to 9H. They are all stamped in silver except for the softest (7B) and the hardest (9H), which are stamped in gold. You can see a folio with all 18 pencils at the Contrapuntalism blog.
Microtomic Van Dyke 600 Drawing Pencil
The Van Dyke drawing pencils with "Microtomic" graphite eventually became Microtomic drawing pencils as seen above. Microtomic was Eberhard Faber’s marketing term used to describe their graphite refining process. The pencil shown below probably dates to the 1940s.
Microtomic 603 Drawing Pencil
Eberhard Faber 1835 Indigo Checking Pencil
These blue pencils could be considered coloured pencils but I think they were intended for copy editing and not for art.
Eberhard Faber 1836 Carmine Checking Pencil
These are a carmine colored pencil intended for checking vice art.
Eberhard Faber Hevi-Check 1836 Red Checking Pencil
The Hevi-Check pencil shares the same number as the checking pencil shown above but is a later version. Eberhard Faber perhaps renamed these pencils to show that they are checking pencils and not to be confused with similar red colored art pencils. The Hevi-check pencil also came in blue (1835 Canada/6535 US), black (US 6339 US) and a red & blue two-color pencil (6540 US).
