Small Surface Scratches on Stock of a Repro

[JoelShep]

I am a new member and new owner of a mint two barrel set Repro DHE 20 ga. I have put maybe 200 rounds through it at the gun club. Unfortunatley, after a cold day I noticed 3 to 4 very small short scratches on the stock. The wood is fine, it just looks like a cat hit the finish with its paw. After some thought I realized my zipper on my vest had not been zipped up enough and must have been the culprit.

Is there a way rub some replacement finish on the stock to fill the small scratches, or should I chalk it up as my mark on the gun? If so, does anyone know what type of finish was used on Repros? Any techniques suggestions would be appreciated as well.

I plan to hunt with it so I know it is not the last ding I will get, but I was just wondering if there is an easy fix.
