Some early engraving was a little crude by today's standards. I will go for the European Grey Partridge on the left lock plate with what looks like a couple of pheasants flying in to join them. The countryside round and about the engraving is typical partridge/pheasant habitat. Some of these primitively engraved partridge are known in the trade a 'flying turnips'. Right lock plate is of course drake mallard and a red fox. Lagopus.....
