While I'm at it here is another less common SA.
U.S. Firearms. Abilene
This one come from the first branch of the family tree that later spawned the Seville and El Dorado revolvers.
This phase of Abilene manufacture was from about 1972 till about 1979 when Mossberg bought and eventually killed the brand.
There was talk of lawsuits by Ruger over Transfer Bar design and a few company realignments so quite a history can be found.
Some have said that this is what Ruger COULD have made ,,,,If Ruger had a custom shop.
Seven & 1/2 inches of high polish ,un-fluted 44Mag goodness.
