Yes, Quite clear. My model 1884 Springfield Trap Door in .45-70 or my Two-hook 12ga Lefever are both antiques even though shells which will fir in them are readily available. Should someone decide to reproduce either, even in the same chambering they would not be antiques.
Likewise if a replica Henry rifle were made chambered for the original .44 RF it would pass under the antique status, but when made for the .44-40 it does not.
Anything made 1898 or earlier is "Antique".
