Job backer 17" jaws - "ets. roger ledevil  - France"

Tightening wheels is threaded left handed.

Foot pedal is used for tightening of the jaws,

set the wheel about 1/2" bigger than book, then depress pedal to lock book in place,

book can than be removed with out adjusting wheel.

Would be very handy in doing edition binding.
