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

Oury J. J.
Here is a Liège revolver for pinfire cartridges, small
grips, folding trigger (so without trigger guard), six shots, 7mm calibre
pinfire and long removable barrel held on the axis of the cylinder by a knurled
screw.
The ELG spangled in oval on the cylinder indicates a
passage to the proofhouse of Liège between 1846 and 1893.
A member of the team managed to see a crowned Z, thus
the countermark of a controller between 1853 and 1877.
5099: Serial number.
A member of the team noted
that the system of fixing the barrel to the frame is reminiscent of the second
Oury J.J.
revolver presented at the page Oury J; J. on te website.
But the
Oury
8300 patent has nothing to do with this revolver.
Nor any patent of the
Mariette
family, also mentioned in the link above.
So the mystery remains whole.
