Looks to me to be nearly the same wording as above.

(16) The term “antique firearm” means—

(A) any firearm (including any firearm with a matchlock, flintlock, percussion cap, or similar type of ignition system) manufactured in or before 1898; or

(B) any replica of any firearm described in subparagraph (A) if such replica—

(i) is not designed or redesigned for using rimfire or conventional centerfire fixed ammunition, or

(ii) uses rimfire or conventional centerfire fixed ammunition which is no longer manufactured in the United States and which is not readily available in the ordinary channels of commercial trade; or ....

Ok Parashooter, I see your point.  If one ignores the parantheses and what it contains, which one should if they don't apply to you, in the first sentence of para (A), one gets:
(A) any firearm manufactured in or before 1898.  And the "or" of subparagraph (B) is not applicable, we're not dealing with replicas.  So maybe I wasn't wrong in my debating with the dealer!  But he probably still won't send it, as he has his own interpretation.
