Does anyone have any information about how to repair old Narishige hydraulic micromanipulators?

18 September 2020 1 5K Report

Models MHW-3 and WR-6 Narishige hydraulic micromanipulator for electrophysiology. The control knob turns OK but produces no movements in the manipulator at the the other end of the hydraulic line. None of the parts seem to be stuck. I have contacted Narishige but because they are older than 10 years they don't calibrate anymore. Does anyone know a company that can calibrate them?
