Found it. The DGJ article was titled "Some American Lightweights", written by Colin McLagen in volume 13, issue 4, winter of 2002. I was wrong about it being a 1/2 frame. The article mentioned the 1/2 frame, but the pictured Parker with the "For Standard Velocity Only" was a 6 lb, 7 oz, 1 frame 12 VH. Stamped the same place on the left barrel near the chamber.
