I have two in very good condition .45 Cal replicas to sell: Flint Lock Dixie Gunworks Tennessee Mountain Rifle with octagon barrel and a matching Flint Lock Kentucky Pistol (Ultra-Hi) pistol, both made by Miroku, Japan. Are they worth anything and do I need a licensed dealer to sell black powder flint lock gun? I reside in NYC. Please let me know and I'll post them with photos on Classifieds. Thanks.
