@trackpin ,
Here is my take on it: Your rifle is obviously made in Italy, based on the stamp. That helps narrow down the search for proofmarks. I'm sorry, but I can't make out that little cypher to the right of
MADE IN ITALY in the first photo. I suspect it may be the manufacturer's cartouche. I think those Wesson rifles were made by Palmetto, but maybe some other forum members can tell us more about that. The letter/number combination on the far right in the first photo is most likely the manufacturer's serial number for that specific firearm.
In the second photo, reading from left to right after the
BLACK POWDER ONLY warning, the first stamp looks like the provisional proof from Gardone (Italy). The other major gunamaking center in that country is Brescia, which has a similar but slightly different proofmark. The
PN under the wreath and star is an Italian proofmark for black powder, with
PN representing
polvera negra, which is Italian for "black powder." The two letters inside the box (
AE) are the date code, indicating the rifle was made in 1979.
These two charts may help. The first one is a cropped screenshot from NRA Museum's database of
Foreign Proofmarks:

The second is a chart of Italian date codes that I got from this forum some time back. I don't remember who posted it, but would gladly give him credit if I knew. It has proven to be very useful:

I hope this helps!
