I've made a decision to send this rifle to the Wyoming Armory in Cody for restoration. As much as I like to work on my own firearms, I knew that this was out of my skill level.
I've spoken to Mark Douglas, the owner, about this rifle. He has access to a pristine original to use as a reference. The Wyoming Armory specializes in working and restoring antique firearms, especially Winchesters. They are able to duplicate the original Winchester case colors. They will also be able to install a properly marked 28-inch-long barrel.
I've spoken to Mark about this rifle, and I feel confident that they will be able to bring this old girl back to her former glory.
Before I shipped the rifle to Cody, I was able to take some pics of her out in the sunshine. I'm still shocked that I now own this rifle.
I stumbled upon Mark's videos years ago before I purchased this rifle. He told me that he intends to make a video of this rifle. I thought that I would share the link on this thread for any of you that might be interested.
