Back in 2002 I bought a Flytec 4020 from the boys at Highland. The paperwork got a little mixed up and I have the Calibration Certificate for Instrument Serial #17346. If anyone has that instument let me know and I'll send you your certificate. Maybe you have the Calibration Certificate for my Instrument ... #22716.
I just hate to throw it out.
