I have a dull black 1936 holster in a group stacked on a show case 3 ft off the floor in a heated, air conditioned basement. Every two weeks I have to wipe off a thin even whitish film from inside and out of this holster. It is the only one in the group of 24 I have that does this. I had 4 to lay on the floor for several months and they didnt have this film. Any ideas?????? I tried to contact Jerry Burney but email came back undeliverable...........
