I'm sorry if I'm not using the right words, but I don't know much about these rifles. Do any of you collect such weapons or have any experience with their value? When I did internet searches, I didn't find any of exactly this year to compare to. Obviously the older they are the more they are worth, I'm just trying to get a better idea. We'd like to make a cabinet and display the two oldest rifles if we don't sell them. But I'm ALSO concerned about keeping them in good condition. Are there special storage/display recommendations? I'm concerned about rust, corrosion, sunlight, rapid humidity changes, etc. Also, it's been some time since it was cleaned and re-oiled. ANy suggestions there for how I should do that and what supplies I need?
