Trying to help a fella over on 16ga.com with his nice O/U
http://www.16ga.com/forum/viewtopic.php?t=6364The smokeless proof is clearly the post-1968 stylized lion over PV BUT the proofdate letter looks to be a 'x' which would be 1945. The Greek 'chi' was not used.

The 'AL' could be Arnold Lochet, but I can't find the ? maker's mark in the 'L' section of the littlegun site or on PeteM's list.
Laurent Lochet-Habran is a bit similar, but it looks more like a 'P' or possibly a 'A' within the 'L'


Thank you and a blessed Thanksgiving to all.
