What thread for Esterbrook nib sections?

[Carl Fisher]

So in my front section thread, Bruce mentioned using the Esterbrook nib sections that have threading on the front. I happened to run across a few Esterbrook units online. A 1550 and a 2668 specifically.

Does anyone know what thred size/pitch these would use if I picked them up to play around with?

Thanks!

Some time in the last year, Shawn Newton organized a group buy of taps for Esterbrook units. It's 9/32-36 (single start).

Shawn might have some left over, or maybe somebody who got one in the buy has no further use for it. The price to get one made was ridiculous, by quantity 12 they were quite reasonable.

Good man! From time to time, folks ask about them here or on FPN, now I know where to refer them.
