I'm a novice at this stuff, especially appraisal and repair.
I spotted a nice looking blue Esterbrook (pretty sure a "J" model) yesterday in a display case, priced $9.50.
I took off the cap, and the fins in the feed were either clogged, or melted together? I didn't try the lever (didn't want something to break
while the owner/consigner was watching me do it).
Assuming everything internal needed replacement, did I save $100 on repairs/parts to get a nice $50 pen? I already have a fixer-upper in green,
that I'll probably haul to the next Chicago show for a pro to look at.
