Well, I have the vacuum sealer. And I have bags. So,
I have a vacuum-sealed Enfield.
The obvious test at this time would be to throw it outside somewhere for a month or two. No, I ain't gonna do that. If I had an old RG revolver or something, sure. However, this does cry out for a test, so...
On the left is no vacuum, just the normally-oiled blade put in a bag and sealed. On the right, vacuumed and sealed. They're both currently buried in the garden, covered so dumbass Security officer(junior) won't dig them up. I hope. Be a bitch to see if the bags worked if I can't find them.
