Description: |
|
An interesting butt gage, with several unusual features. This
gage uses a telescoping arm with one point on the tube and one in
the inner arm, and a large metal head with a slot to fit the
inner point. Interestingly, this tool does not automatically
account for the hinge gain (unlike most other butt gages).
