The rare Stark No. 1 watchmakers' lathe with a beautiful "miniature WW" prismatic-type bed. 81/16" long and slightly under 1" in diameter. The headstock appears to have been fitted with the usual type of hardened, ground and lapped steel conical bearings with the spindle accepting 4.7 mm collets (other collet dimensions and thread pitches are listed below).
The single headstock pulley, simple push tailstock spindle - and economical black paint finish - may signify a lathe originally intended for repetition production work
