PCU5000X Jihostroj Propeller Governor P-510-036/A
Clockwise rotation; 0.886:1 ratio; 2338rpm.
This was purchased from the US as a new governor to suit a counterweighted propeller on a Lycoming. Apparently they lied so check that it suits your application better than I did… As far as I can tell it would suit a custom mount on a rear engine pad on a Lycoming or use in an automotive conversion.
The governor has recently been inspected and tested and it is in new condition.
These retail for USD$1600 from places like Aircraft Spruce plus shipping and import duty, so my loss is your gain.
Will post worldwide so contact me for a shipping price if required.
