There is no doubt that in this forum exists a lot of knowleadge; Rockdoc you are completly right: behind the opening lever is a hiden lever that allows to remove the barrels.
Both, the barrels and the reciver have several similar marks, like P.V. and other letters (I remeber U) with a point in the upper part. The barrels also have the weight in kilograms, the chokes in milimeters (both barrels are IC at 15.9 15.8) and the gauge 20-65 in an oval.
There are another marks in the reciver, like what seems to be a very little rampant lion, but I am not sure.
The problem is that my camera is the point and shot variety and do not have any close up divise; what can I do?

Thank you for sharing what you know.

Best regards,

Jose
