1886, 1892, 1894 questions from Newbe|Winchester Rifles|Forum|Winchester Collector

Good day,

I was inherited a few models 1886, 1892,1894, among others.

We believe we have the dates and some description of the importance.

I believe the first thing is to get some letters of authenticity, I learned this after Ruger stopped producing the LOA

The model 94 25-30 #4920xx was refurbished and is a little to shiny? Not sure if we shoot.

Is there ideas how to clean these up to keep the history going. They seem to have lost all the color?

We wanted to shoot other of his old guns but they all had issues and when I sent a few to a gunsmith to have them cleaned and fixed, the same problem happened. Especially the double loading?  I have to say this place didn’t have much other than plastic guns. It was a concern cause it had 2 bullets jammed in the chamber. They all seem solid but I don’t want to have issues again when I load them up. I want to prevent this if it’s still possible to shoot these. Or do they stay in a safe?
