        Description: |  
| 
    This is an intersting combination marking gage and trammel with a
    reversible head to allow it to mark off straight or curved edges.
    Of particular merit on this piece is the presence of gaging holes
    on the back of the arm, with a corresponding index pin in the head.
    This would allow the gage to be quickly and accurately locked in
    position at standard distances.
