The rings are original Leupold ones fitted to the Hannibal for their long eye relief scope option but the scope is a Simmons 2.5x20 #21005 shotgun/rifle scope. As can be seen from the image below the name on your scope has either worn off or been removed and the Simmons is a replacement for the original Leupold scope. I doubt A-Square would have fitted cheap Simmons scopes to their Hannibal rifles.

I have a nice original Leupold 2x EER scope on my Mauser 404J which would work a treat on your Hannibal but unfortunately we are in the wrong countries to do a deal.
