Grover, appreciate the quick response to my query. After adjusting the bifocals (the main problem) and having the light shine across the prop hub the following info was available. Original prop was stamped 7351. This was later changed to 7149, which according to the Univar is for climb or high altitude operation. Since the plane originally came from the western part of Texas, I take it that was when the prop was reworked,since there is no indication in the engine or airframe log to indicate any damage or prop strikes. I did query McCauley to see what they suggested or to see if they have an alternative prop that might be better suited... I do have a shade panel but have not installed as yet, the spring weather will not be to far off, I hope. Thanks again for the info and Happy Couping
