Chris, sounds like you are describing a standard jr sized Musso surface swimmer. It uses a Lefty 2 midslot (which should be called Musso 2 since Lefty just took it from Musso).
Musso didn't build one like I have shown. He did build a small swimmer for personal use that he never sold. I've since learned it was a fatter plug and used a full sized lip. I think there is a picture of it in the Pinaturo articles. It only had one belly hook.
These plugs were originally something I dreamed up and described in this thread a few years back
http://www.striped-bass.com/Stripert...structive.html. The dimensions are in there somewhere. I know Fred (eskimo) built a variation that worked for him. Somebody else actually copied them and was selling them over on the saltwater edge forum a year or two ago.
You can use a lefty 1 midslot for surface use, but they also work very well with a lefty 1 high slot lip and swim as deep as a little conrad set up that way. The ones I built used a small belly weight and tiny tail weight. I like 'em better than the small danny surface swimmer although that plug fishes pretty well itself
