[GreenKeys] OFF TOPIC - But related- WTB Mechanical calculators

[Bruce Gentry]

I have had my interest revived in four or more function mechanical 
calculators with the moving carriage made by SCM, Marchant, or Friden. 
I'm most interested in the  very last ones they made with the 1960s 
style cases such as the SCM/Marchant Figuremaster and the Friden SVE. To 
keep on topic, wasn't Klienschmidt once owned or affiliated with SCM? 
Thanks,
