I believe the star here is the key. I think that makes it a better grouping rifle than normal. Maybe I am wrong but I do think that is what it stood for. I get the old marks wrong all the time. I do believe the newer kimber rifles also used a star on rifles that grouped better than average on model 82 and 84's like the super America. It might have been a custom order for the star but they did not put it on there for nothing.
Either way you got 4 nice choices. For the money I would look at the a-dl just because I like that rifle. It would also be the newest of the four and most likely the one they would deal on.
Thanks jmarriott. The A-DL is a 30-30,blue and varnish 90-95%. It is a G pre fix but the waffle top is tapped for a scope. Not sure if this is original as I read on this site 1955 they started to drill and tap the receiver. It sure looks factory because from the blueing and untouched screws,it appears to never have had a scope base mounted.He is asking $475.
