Hi Mark, I call such a Luger a "semi-shooter". It's all matching, but with a poor finish. I would price it above a shooter, but well below a collectable.
Since most 1939 Code 42 Lugers didn't have numbered grips, a decent pair of un-numbered or a pair of post war grips would be correct.
The grips aren't worth much, IMO.
Good Luck!
