More surprises coming from the Police pistol I initially posted. The owner brought in a cut down police holster, which was captured with the gun, but heavily altered into a shoulder holster by the GI who captured it, (The GI was Thomas A Owens, 1922-2010, who wrote a book about his experiences called "An ordinary man in extraordinary times").

The holster is marked A. Fisher, Berlin C2, 1929, has the police sunburst and police Unit mark L.33.133, (overstamped and obscured and only partially readable).
Also there is a spare magazine, aluminum bottom, marked "3" at the top, 6296, no suffix, "+" and has what looks like a starburst and K as a proof. The aluminum bottom seems to also have a strange insert, like later mags, visible only on one side.
There were also several ammunition boxes; one WW1, several WW2 and one 1943 dated .22 box.
