Spent $75 to confirm this (it has been eating at me for over a year). Pictured are an exact copy of a Musso Pine Senior on the left.....which uses a Pikie 3 lip (exactly---I borrowed an original and traced it) , and an original Musso Senior Surface Swimmer on the right which uses a "large" Lefty mid-slot lip (exactly). Note that both lips are mounted above midline although I am not sure if this was always the case.
Unrigged the plug weighs 2.75 oz.
Now I am happy
