Al Parker was first to home build and fly the HP-14. I believe it was the first non Schreder built HP-14. I had Al remove over 135 pounds of paint before I purchased it. I flew it just finished in primer surfacer. I purchased HP-14 N6343B from Al Parker in 1969 and flew it for about 2.5 years, 531 hours, about 10,000 miles cross country and in airshows performing inverted spins, vertical rolls, and such.
