Balance in Transition II

As previously discussed, a marble Sheaffer Balance with a rigid radius clip was a pencil in transition.  (See my blog, Balance In Transition ) Further light has been shed on the idea by an ad for Sheaffer pens, below, from May 1937 in which we see a rigid radius clip pen made of "ebonized pearl" celluloid next to one with striated celluloid.  Clearly from 1936 through 1937, the two celluloid patterns ran together for the Sheaffer Balance pens and presumably for the matching pencils.

I happily came upon another example of the ebonized pearl Balance pencil with the longer rigid radius clip, this time in a monochromatic color scheme of black and grey pearl, with silver trim.  The black and grey ebonized pearl does not have the plain black top and tip.  This is the largest size Balance pencil measuring 5 & 5/8 inches, and, like the smaller transitional black and blue ebonized pearl Balance, has the imprint with the patent number and uses 1.1 mm lead.  This is also a lifetime warranty pen's companion.

Below you can see a large striated rigid radius pencil alongside this pearl pencil.

And here is a better view of the clips and center bands.

They balance each other nicely.
