Need close up pics before I'd give any suggestion, but if in doubt - leave it alone and think on it.

I've seen the original finish on high quality 30's 99R's vary somewhat, but mostly a darker brown. Here's some prewar R's and to the best of my knowledge none of them have been refinished, but top 2 and bottom rifles are the best condition.
