I am unable to definitively identify the manufacturer as there are no visible identification marks - only numbers on the hub assembly – 52282e and 59346.
If anyone has accurate information on this propeller I will update this post.
My father was in the Air Force for 42 years and also owned an aircraft parts company.
This propeller/hub assembly was was rebuilt and certified about 15+ years ago and was never installed on any aircraft – I have not located the yellow overhaul service tag. Regardless, it will need to be re-overhauled and re-certified as it sat in a warehouse for 15+ years.
