Hi All,
Here is a large cast iron Guillotine type tool that we got if France recently on our last buying trip along with two nice book presses.

I have no idea what this is for, it seems to have a shaving action (uses an old peugeot freres block plane iron); the second cutter is at right angle to the first and has a ruler scale.
Ideas so far are Printers leading cutter, Stained Glass lead channel cutter or some sort of leather trimmer.
All ideas welcome 
Regards,
martin
