Plain Lever-action Tailstock with rack-feed barrel and adjustable depth stop. This tailstock was also available mounted on a "cross slide" unit.

Half-Open Tailstock - designed for light manufacturing work where quick interchange of spindles and tools was required.

"Quill Rest"
This special fitting was designed  for extremely accurate work and placed just in front of the headstock and driven from it.
The top of the tailstock was arranged to hinge open to allow the rapid changing of quills which were available in two styles,  the "chuck" type, the front end of which was a duplicate of the headstock spindle, and the "faceplate" type which was available with either tapped holes (1/4"  -20 U.S.F. arranged in eight rows) or T slots.

Quill Driver - pulled into headstock by standard draw tube

Faceplate type Quill

Index Pawl and Block
This accessory could be used either on the headstock or the Quill Rest. An index pawl unit was clamped to the bed and the Index Plate (shown below) mounted above it on either the rear of the headstock spindle - or on any of the Quill Rest quills.
