This is a rarely seen early Allcock bait. I can’t remember ever seeing one, although they do exist because this is one of them.
From the 1870’s catalogue this is listed as the Shah lure. A 2-1/2” long hollow metal body bait with tiny little fluted almost rivet type decoration on the outer body. This must have caused some vibration as it was retrieved, maybe that was the idea.
The usual Allcock early metal fins and a wire gimp hook mount set for the period are complete and original too.
This lure was sourced by a tackle dealer/collector at an antique market and whilst it wasn’t cheap by any means, it just shows it’s still out there.
