I had the good fortune to try out an Esterbrook for the better part of a week and have really taken a liking to it. It led me to purchase a couple, though only one is in hand at this time.
Gray LJ w/9550 nib
As far as I can tell, based on the spade shaped lever, it is an early LJ Double Jewel instead of a let model with the spoon lever. The imprint has the ® mark after Esterbrook, suggesting it isn't the earliest of pens. I am trying to get a handle on the different varieties of J Series pens and pencils. There seems to be a significant amount of information regarding the Fountain Pens, but information on ball-point pens and pencils has proven to be really challenging.
I would like to learn more about the B, A, and H "Dollar" Esterbrook pens and pencils. Were they labeled as something more than B, A, or H, based on color, pen/pencil, or something else?
I have read most of the information on esterbrook.net and richardspens.com. Certainly, I would appreciate being pointed to any additional references and resources.
