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

Edouard Kettner (perhaps)
The weapon being much known I do not detail it!
Remain the mark which is unknown for me.
The “Who’s Who” does not deliver any information to me, no arms manufacturer does not correspond to EK except Edouard KETTNER present in Liege in 1892! (Yes it is well the founder of house KETTNER always in activity!).
I however do not have any base to affirm that it is indeed its mark!
