Lee J. - found the reference in Paulson's book.
Under the chapter heading "THE HUSH PUPPY".
"The Hush Puppy was issued with a modified, steel framed Smith & Wesson Model 39 pistol. The Navy named the experimental eight-shot weapon the WOX-13A Pistol. It featured elevated sights to see over the suppressor, a threaded 5 inch barrel and a detachable tubular shoulder stock....
...Lee Juras of the Super Vel Cartridge Corporation developed a 159gr FMJ bullet for this system....
By the end of 1968, Smith & Wesson had developed an improved pistol with double column, 13 round magazine to solve these problems."
So you can see how/why I was curious.
