The granddaddy is the Star DK "Starfire."
It's the gun the Colt copied, and was the original Colt "Pony," though very few were made as such. The Star design then became the F.I. model "D", with a steel frame in place of the original aluminum alloy. The model "D" then morphed into the almost identical Iver Johnson "Pony" .380.
Just so you know.
