It's funny, but when I was a kid my Dad hunted with a Model 70 that had a 4x Bushnell Banner on it (I'm 57 now). When he got a Remington 700 he moved the Bushnell to it, and later swapped it out for some cheaper scope that was variable power. We put the Bushnell on my single-shot .22 and I used it for years, eventually taking it off and putting that same variable-power scope on it.
That Bushnell languished in his closet for many, many years, and when he passed away I brought it back to CO along with a lot of his other stuff. Just a few weeks ago I decided to get my Winchester .44 Trapper ready for my first deer hunt, and decided to put a scope on it. So, I dug out the old Bushnell, cleaned it up and mounted it on the Winnie.
I'm very happy to say that scope works perfectly on that Trapper, it's still just as clear and sharp as it can be, and I think that scope may actually be happy to be back in use again! I had some accuracy issues, but that turned out to be the lead bullets in my handloads. With jacketed bullets, that Winchester and Bushnell combo is quite formidable at 100 yards, I was very surprised.
Sorry for the thread drift, I'm just very happy with the resurrection of this God-only-knows-how-old-it-is 4x Banner, and had to tell the story! I'd assumed it was no good for years, but a piece of lens tissue and a good wipedown was all it needed. I'm even using the same ancient Weaver rings that have been on it all these years. I'll be thrilled to hunt with the same old scope my Dad used to hunt with 50 years ago, I'm sure he'd smile too.
