WANTED !!! AN ANTIQUE FLINTLOCK PISTOL PLEASE.

I need an antique smoothbore flintlock pistol, preferably .60 to .62 caliber but will settle for smaller or larger. Any condition considered, I don't mind doing some repair work.
I am prepared obviously to pay a handlers fee plus freight costs. No licence, registration or permit to purchase is required here in NSW Australia.

This is the sort of pistol I am looking for. Preferably 18th century, but would settle for earlier or later.
Regards, Keith.
