This long piano — 54-inches — hinge appears to be nickel-plated brass for it does not stick to a magnet. It is heavy, not light weight. The hinge has been used; it is an old one. It is in very good condition.
The hinge measures one inch wide, across both wings. Each wing is 1/2 inch wide.
This is a fine, hard-to-find hinge. No screws are included with this one.
