I ask this question on a American Airgun forum. Curious how the British would view it?

“This to me has become a fascinating question. I am a collector more than a shooter and I find original condition very important to me in evaluating price and desirability. I have heard that years ago refinishing was pretty accepted but now that seems to have changed. I would rather have a gun with legitimate wear than one refinished to look new. I know many here are just shooters and that’s fine but curious thoughts on how this influences other collectors. I know in the vintage firearm world a refinish can just destroy value. I feel in the Airgun world it may be more of a mixed bag?”
