I believe they refer to it as a Rampant Lion over the PV mark is a smokeless powder proof. This would NOT be proofed for SAAMI spec shells.
Normally on a Belgian gun, the word choke means it has at least 0.2 mm (.008") constriction. If the actual amount of choke is specified it will normally be written as a fraction IE 18.5/18.3 which would indicate 0.2 mm of choke. I would have to dig out some books to give the date this style of marking was used, but do not be surprised if at least one barrel, maybe both, is a full choke.
The 18.2 was likely marked at a preliminary proof & then the bore polished enlarging it to 18.3 prior to final proof. This would indicate a bore a bit under nominal .729" @ .720".
