NSI gearboxes


Yamaha gyro...Oregon, USA
I'm posting this for a local gyro guy: Anyone know the approximate cost of these NSI gearboxes (out of business now) when they were new? I believe they were used mostly w/ the Subaru automobile engine conversions for aircraft.

Please contact Bill Totten @ 503-seven zero one, 61seven8.
