Mine is pert dern in the middle of your two....side swivel, OIL finish stock. Mine's a KSI, but that probably doesn't matter.
Transition years are a pain to try to restore. 10m is a neat year for that kinda conundrum....
I don't think I have come across ANY side swivel stocks that were unserialed replacements. I have been lurking in a low priority fashion for one for years...and I don't even think I have seen one that was too spendy that kept me away, I just don't believe I have seen one at all.
Best of luck!
