Maker: Eagle
I am somewhat tentative in this identification, as the only catalogue I’ve got access to is for 1937. The lettering on the clip doesn’t quite agree with that source
Production Run: c.1935 – c. 1940 (tentative in the extreme).
Cost When New: $1.00 assuming I’m right on the model (for modern value, try this calculator)
Size: Um… I forgot to measure it before it went back to its owner. Biggish.
Point: 14k gold.
Filler: Lever.
Note that the point is replaced with one from a Vacumatic. This image is not to the same scale as most portraits.
