Antique Lark Lure
I love these items, they are such a talking piece. The Lure was pushed into the ground and the head turned by pulling a thread hile the user hid in a bush nearby. Apparently the flashing of the rotating mirrors replicates the courtship markings from of a Skylark from above. The rival birds could then be shot with fine shot when they approached.
This Lure has a tin spike, some blue mirrors and original string holder
