After looking at an enlargement of the latest photo, I'm less inclined to believe the first mark was P.Bg. Whatever it was, it was x'd out, leaving the weapon number that was re-used in the mark PB.691. by the police school at Bonn. At some later time, both sets of marks were lined out.
Perhaps the first mark was some non-standard mark used by the Bonn school between its founding in 1926 and the issue of the 1932 marking instructions in Manual 40a.
