Dragon Fly Door Knocker
A good quality Dragon Fly front door knocker with separate strike plate. This example is unlacquered, so will tarnish down pretty quickly.
These are actually new old stock, so they've had a light polish, some of the nuts/bolts & strike plates may slightly differ to those pictured (washer are included, not shown).
