Serial number 30249 would date to 1883.

The gun appears to be stocked to shoot from a head up stance at birds rising from ground level.

My guess is that it was built as a live pigeon competition gun, heavy enough to absorb the recoil over a 100 bird event.

Greener’s continued to build single barrel Anson and Deeley (and Facile Princeps) trap guns, showing a 40 Guinea model in their 1923 catalogue.
