Unfortunately we dont have any records which would have told us so much. Without them I think we are only guessing. The basic guns only had a little scroll engraving, the mid range guns had a less detailed dog and a bird which we call the Perrins Bird, rather like plump partridge with a long beak and then the top quality guns had a much more detailed dog with recognisable pheasants and partridges. Any thoughts would be welcome.
I can't just find a close up of the 'Perrins Bird' but this is the less detailed dog and some kind of water fowl - bet they didn't have any truck with non toxic shot???
