The NPF mark is distinctive, Austria with a Ferlach proof.
The rest of the marks are not described in the one book I have with a chapter of Austrian proof marks, but my first read would be:
8.9 => 9mm caliber, proofed with a 13.25 g (204 gr) bullet
proof done Jul 1929 with 30% overload
F 135 - the right choice
