P-10 Speedraft

(wooden barrel*)

Keuffel & Esser, New Jersey, U.S.A.

lead diameter mechanism composition variations production date origin	2 mm twist-lock clutch wooden barrel*, metal mechanism none 1950s USA		* The barrel composition is very unusual. It appears to be wooden, although the finish is such that there is no trace of wood grain. Also, the intricacy of the machining required (see black plastic P-10) makes me skeptical this barrel really is wood.
