The round Gandalf belt buckle on the left is made by the John E. McCann Buckle Co. of Wenham, MA. And I need the Bilbo and Frodo versions to go with Gandalf. These buckles are made of pewter as a lot of these buckles are.
The next Gandalf buckle is made by The Perth Buckle Co. in 1978
The other buckle is just a cool looking wizard type buckle that could be Gandalf or even Merlin maybe. It is a 1979 version N-145 from the Bergamont Brass Works even though this buckle appears to be made of pewter.
And the last buckle is a brass Merlin made by The Beardsley Buckle Co. of Bloomington, Indiana.
