Mergus By Mathan Merian? Fine coloured engraving of 4 species of Ducks 

untitled Monegrams Of Mathan Merian for the

 Encyclopaedia Londinensis 1817 with very small

 signature J. Pass s.c. 

The engraving could stand a light cleaning but we did not wish to remove it from the frame in which it is nicely mounted.
