I am having a bit of trouble with my old worn out eyes reading the diameters. Is one barrel marked 16.o & the other 15.9 or does each barrel carry both diameter markings. If the former then the mark indicates the dia of that particular barrel & it was choked to at least .2mm (about .008") but could well be considerably more.
If the later then the smaller number would indicate bore dia at provisional proof & the larger the bore size after final finishing for definitive proof. Choke would be same as above.
Earlier Belgian proof did indicate both bore & choke diameters but this had been discontinued.

Miller,

One barrel shows "16.0 CHOKE 15.9" and the other barrel merely states "CHOKE 15.9"

Does anyone have any thoughts on the strange mechanism behind the ejector "hammers" on the forend? It slides forward and back.

Additionally, I have never seen this before, but in the picture of the trigger/trigger guard, you can see a small square piece of metal protruding from under the trigger guard. When I apply the safety on and off, I can see it rotate slightly so I assume it is somehow related to the safety, but it seems so strange!

It is your ejector cocking slide. On closing the slide abuts against the knuckle step and pushed the ejector tumblers back into full cock. This system is supposed to prevent cocking via the breech face and thus saves wear and tear on the face.

As you noticed though it has a rather hard feel at the start of closing and a sudden snap home once the tumblers have gone into full cock.

My SXS boxlock is Italian and has the same system. Has been trouble free for 35 years.

My take on this is the barrel with 2 numbers had its bore enlarged by that 0.1 mm in finishing, the other did not. As .1 mm is about .004" this would be the enlargement. I have serious doubts this gun left the factory with 0.0/0.1 mm chokes, especially as the Belgian proof house did not normally mark Choke unless the bore had at least 0.2 mm (about .008") of choke.
I believe my original assessment is still correct & this gun left the factory with at least 0.008" of choke could be much more.

Miller,

That makes a lot of sense. Thanks for the explanation. I had never seen that mechanism before on any of my other guns...

fallschirmjaeger, I have a Belgian gun very similar to yours, also a 20ga. It was proofed in 1930. It has the same mechanisms as your for the ejectors and safety. I have shot the gun A LOT at clays and quail and it has given me no trouble over the years.

I hope you enjoy you're new gun as much.----Matt
