Kuhlmann Pantograph Need

[Flightmap]

i was given a Kuhlmann GM II 3D pantograph. It has the milling or cutting spindle (with one collet), The operating handbook, and the 3D tracer arm.

I need help with acquiring: a tracer spindle. A book on industrial pantographs. Collets. And obviously lettering fonts

Any body have a damaged machine that I could recover parts from?
Books?

Thanks, Ken

The collets are a "type b" 260 collet. I don't know what these are. Does anyone know?
