p-08 marking on frame

[renaissance]

Just saw a luger at my gun shop range
Guy was picking it up on a transfer
Under the circumstances I couldn't get as close a look at it as I wanted

It came with "bring back papers" - dated 1945
Name was "Pasternack"
Name sounded familiar but couldnt place it
It was a "42"

Some idiot had it "chromed"

I caught glimpse of a "P-08" stamped on the left side of the frame
Just forward of the Safety

I don't remember seeing this marking before

Neither of my "42's" have it

Is it legitimate ??

What does it mean
