I agree, the last one is the nicest of the three. You might want to consider really giving it a good cleaning to remove the deep seated rust and then having it restained to raise the pamor again. The pattern will probably rise much clearer than it is now. Probably not anywhere near #2, but it should get clearer. Then you can get that gold ready.
#1 and #3 look 19th century, but #2 looks like it could be mid 20thC. I think it may have been made more as a looker than a fighter.
