O'Connor's pressure article first appeared in the Speer #4 manual published in'59. At that time it was credited as being reprinted from the June '56 OL.

Jack was given credit in the Speer manuals from #1 in '54. I hope most of you realize that he lived "just minutes away" from the Speer facilities and was a frequent hunting partner of Vernon Speer. He often wrote that he utilized their facilities on numerous occasions.

Good shooting.
