survivor?

I found this trail horse at auction. Its a GTO110, code#39070113, with a Tecumseh 21/2 HP, model#H25-25173G. It appears to be an orginal survivor?

I picked up this old Trail Horse. All original. She had lots of rust. Cleaned her up as good as I could. Some spots, the rust ate through the paint. My question?? I have cleaned it more since this photo. But, you get the idea. Is it a disservice to clear it to maintain what is left or just...
