Looking for original owner 1971 911 s 9111300570 philly area

Hi Guys !!
Just a note to see if anyone (old timer !!) might know the original owner of my 1971 911 S 9111300570. The car was bought new at Holbert's in Warrington, PA 5-4-71 and traded at Algar Porsche 5-6-72 with 11193 miles. It is silver metallic with black interior. I am in the midst of restoration and would appreciate any leads or names of guys who would have been active with PCA at that time. Thanks for your time !!! George Kehler in Tennessee
