I used silicone treated socks / bags long ago but have come to prefer the VCI treated Gun Socks.
You guessed correctly...The numbers correspond to my logbook......Ben
This is the main reason I still do the occasional three table gun show - it's the only chance I get to visit my own guns...Even then there's no room for all of them...I occasionally come across a gun I had forgotten about...This summer I made the effort to take every gun out, wipe it down completely with a dry rag (that's all that's needed with a RenWaxed gun) and make a complete photo file on each one including the boxes and presentation cases...That way I can at least go back and refresh my memory on what I have...The big drawback for me is when I go looking for a certain gun it takes forever to find it.
