I have the manual on all five Leabarjan models, but I am away from
home 'till the end of this week.  I made my own perforator based on
the Leabarjan with improvements, using a cranking device to advance
the 'time' scale.  This is necessary for reasonable speed, as it
takes forever and a day to use the slot/notch device.

I can furnish some detail on this if need be, with photographs from
the Leabarjan manual and my own perforator.
