You just can't tell with some of them. A topnotch refinish guy these days- bowdoc for sure - makes it better than new! So good, you'd never confuse the old with the new. I used to rehab a few bows, and have spot-finished a problem or two ..... but not to mislead a buyer. As stated on another thread, I don't consider a professional cosmetic repair to be bad, if it is openly recorded at the sale.
That said, I picked up a 1971 Grizzly at an auction last week that is also like new, finish-wise. So good that I had to wonder....but, here's the deal: with all due respect to your bow-and mine- there's simply very little incentive to refurb a 1970 or '71 Grizzly without stating that it's been done. What are you gonna have when you're done? A real good 1971 Grizzly! Not a shabby bow, maybe, but not payoff for deceit.
I've collected old bows since 1980. Some turned out good -some didn't. Some must have been misrepresented..or worse. Doesn't matter. Some were better business deals than others....some went-honorably-to new homes. If you never sold one with an undisclosed defect, that's all that matters to me.
I hope your "new" bow shoots as good as it looks. If it doesn't, then you "get" to find another new bow! (No offense....the chase has always been fun for me.)
