For your consideration is this high-precision Taft Peirce parallel block.
This is the inspection grade model 9151-2, which retails for nearly $500 new. Made of steel, carburized and hardened to Rockwell “C” 58-60. This is in good condition with some wear and minor surface darkening. This has a slight magnetic attraction.
Included with this is an Anton 1x2x3″ parallel bar. This is also in good condition.
Each measures 1″x2″x3″.
Please see the photos for more detail.
