I often read the repair section of this and other forums. Last night I read one plea for help with an Esterbrook and it was because the owner had been to rough in trying to restore. The Esterbrook appears to be the height of form and function. The simplicity of a j bar, that is easily replaced, and a ink bladdler we call a sac never fails until disuse and time destroy the latex. The pens just work even if near 90 years old once the simple mechanism is replaced or cleaned.

Esterbrook plastic has to be the best. It does not crack over time or become brittle from what I've see on the 1940's and '50's pens.

Is there another brand that offers the ability to change the pen by a simple nib swap? Perhaps??
