Back on December 9, I provided closer views of the enamel-over-brass checking pencils made by Wahl Eversharp from 1922 until around 1929:
Unfortunately, I still haven't been able to track down a blue one. However, at the Baltimore show, Joe Nemecek was showing off his loot to me on Sunday, and here's one of his finds:
Note that the trim on this example is gold filled rather than nickel plate. Joe's pencil is also enamel over brass, and the paint is just flawless. But wait a tick -- that tip doesn't look like a checking pencil:
Joe's is a standard Eversharp pencil, not a checking pencil. First one I've seen -- great find, Joe!
