Can These Grips Be Saved?

[PEB]

Hi All
I just recently purchased a 36 Mauser Luger that is going to be my shooter. It seems an owner at one point decided it was a good idea to paint the grips black. The gun seems to be all matching but I do not see any number on the grips. I would like the wood checkered look for this pistol but don't know if these can be saved or if it is even worth it.

Any help is greatly appreciated!!!

Thanks
Paul
