On the discussions here I have never seen the Belgian reworks meantioned.
I belive those reworks was done just after ww2 maybe into the 50th bu I dont know.
A number of those guns was shipped to Sweden to be used as targetguns and for the company militias that the bigger more important companys had at the time.
I have no idea if those guns is all kinds of parts assembled in one gun or if the parts belonged togheter since before.
I have seen those guns both with and without
makers name, year of manuffacture, and other otherwise original stamps.
All guns I have seen have been supplied with Swiss m29 mags.
I have a few pics that I included on one.
