Correction to the afore: that's Aircraft Accessories, also in Tulsa Oklahoma just down the street from aircraft specialties. I can never remember which name goes to which shop. Anyway they were also very good to me.

I also have my governor at H and S at the moment. Mathew there is a great guy and they do all my propeller work. They are the ones that seem to be able to get the parts to service the old style propellers.

Hi Gray,
Thanks for the information! I installed a used 210443 governor which works fine, but I will now have time to get my old one fixed and have eventually a spare one.
