Some of the most beautiful work of this craftsman, and many others, are in this book “Liège Gunmakers through their Work. 1800 - 1950”.

As for 
the letters on the carcass under the right plate, another member of the team 
linked them to J. M. Dery. Here is the result of his research 
which can be related to the brand J. M. D. (identified in the 
files of another member of the team, unfortunately deceased) as being “Dery 
J. M. & Cie.”.
A 
genealogy site allowed to know a little more: Jean Michel Dery 
- Manufacturer of arms - Born on August 16, 1849 in Wandre.
Married 
on November 9, 1883, in Wandre, to Marie Elisabeth D’Heure.
It links 
him to Mr. Dery. -D’Heur (probably her son, with an “e” minus), registered at 
Proofhouse of Liège between 1899 and 1919, etc. on page 71 of the “Who is who of 
the Liège armoury”.
