After reading this thread, I had to go take a look at my great grandfathers Winchester 1890 & 1892 rifles that I had inherited about 20 years ago from my father. I cleaned, oiled and dryed them about 20 years ago and just put them up on my wall rack. I also have my Browning Automatic shotgun hung up there also and really, none of them look any worse for wear, other than a heavy coat of dust.
I know this is not ideal storage for a collector gun, but for weapons that were used and cared for and then cleaned and hung on the wall, they really don't look that bad.
I have a few other guns in padded gun bags, including my dad's Browning, which I might take a peek at shortly.
I had no idea the "oilguy" had such an active weapon forum.
Thanks for the heads up and I guess it's time to do the 20 year cleaning of my small armory.
