Grips on byf 42 Luger

[Balder]

Gentlemen,

I have inherited a 1942 Mauser byf Luger from a relative who recently died. He disarmed a German NCO or officer during the liberation of Norway in May 1945 and has had it ever since. It is all matching and in pretty good shape, although I was at first a bit disappointed with the black plastic (bakelite?) grips. Then I came to think of the fact that I haven't seen too many plastic grips and then only on VOPO Lugers that came out of former East Germany. I assume that these grips are the original ones since it's been in the family since 1945. The magazine is fxo and the pistol came with a very nice brown Luger holster made by R. Ehrhardt in 1939. Does anybody know more about this gun in general and its grips in particular? There are no markings present on the grips.
I can post more pictures if necessary.

Thanks!

Balder
