Have you not had any trouble with storing in the holsters?The "black widow" & "brown recluse" lugers really do exist and I have some in my hide out safe, where they have slept for more than 40 years. The holsters they sleep in are all original and date stamped on the back side 41 & 42, one holster contains a luger tool with the eagle acceptance stamp. While all this has slept in the safe it has increased in paper value more than 100 times what I gave for them 40+ years ago. A "G" date all matching luger sleeps in a commercial holster stamped on the back with the luger's serial number. I paid $700 for that set about 30 years ago.
No mildew . . .or other maladies?
