The big hang up for me is wood that's been "cleaned up". And as much as I love old Winnies, the DuCo laquer wood finish used at the time was not the best. I've got a 270 SG in the box and it has dust nibs and minor sanding scratches in the stock. The finish is so soft that how they've been wiped or cleaned over the years can change what the wood looks like. They get shinier with age and wiping so for me I look for that. The finish on the repro stock on GB wouldn't fool a serious collector.
