I am reliably informed that this 5" striated celluloid repeater pencil with 1.1 mm lead is related to the J-Series pens made by Esterbrook. It falls within the "transitional" period of 1944-1947, and probably toward the end of that time. The color is called "copper," and is nicer in person, a lot like figured cherry or maplewood.
The imprint is the only clue to its origin, so here is it is highlighted to be more visible.
The clips of some Esterbrooks have the name on them, but not this one. Here is a look at the washer clip and the black "jewel" end, which, interestingly enough, screws off. The cap removes to reveal an eraser.
Here's a better view of the imprint, which says Esterbrook, Made in U.S.A., and the center band.
The tip shows some ribbing for grip, and you can see the lead gripping mechanism, too.
