Art Deco Pen Holder

I have been searching all over for something to display my Egyptian Revival pen and pencil set, and I found this today. What better than a Pyramid?!! It's certainly not perfect, but it is deco. Someday when it's above freezing, I'll go to the exotic wood store, pick up some ebony, and make a nice one. As the song says, It'll do until the real thing comes along.
The piece itself is an Isosceles Triangle. (I know, greek and not Egyptian, but what the hey!). 4 3/8" on 2 sides and 4" in the front and 2 1/2" tall. The tray says Made in USA, and there is a 2 on the bottom. It appears to be the type of Bakelite they used to make the old phones If soneone has any info on the manufacturer, I'd love to know. Thanks for looking!
