Chemist, I found this random comment wandering on the internet.
No idea how valid it is though.
On the left hand side of the barrels' monobloc near the ejectors, you will
see some " * ", " $ " and " - " markings. These indicate original Belgian
factory choke designations.

Norton,
these markings are markings found on browning guns. The one you described is a skeet choke o/u. The browning auto 5 that did not have chokes is marked on the barrel full, mod. or improved cylinder or whatever in plain English. .
Well, my Belgium A5's choke is not marked anywhere in plain english as you suggest.
It is marked * special on the RH side of the barrel and marked "E LG *" and "12-75*" on the left hand side.
No where is the choke clearly stamped.
A few years ago, there was a CGN user that knew everything about our A5's, wish he was still here.
All questions would have already been answered.
