Great story thanks for sharing... Boy been there and done that. My shop is infested with little Gnomes and when something hits the floor they scurry out from everywhere and drag things away to parts unknown. I always seem to find where they store them 2 weeks after the replacement parts come in or a month after I sold the gun...

I think the Gnomes get tired of playing with the parts and slide them out where I can find them, usually in plain sight.
After a few incidents like this, usually of my own doing from knocking those containers on the floor, i have gone to putting parts in strictly freezer ziplock bags. The heavier ones. This does a number of things.. It allows me to
1. See exactly what is in the bag without opening it (a real plus for butter fingers me).
2. I can study the parts without opening the bag and loosing them (see #1 above).
3. It I am disassembling the action I can do it in the bag with it partially zipped so anything that goes flying or falls out stays in the bag.
4. I can compare parts without opening the bag and loosing them.
5. I can easily add to the parts in the bag if necessary.
6. They are easy to keep track of and you can mark what in them with a magic marker.
7. They are realitively inexpensive as compared to buying replacement parts.
8. And best of all, my wife can't figure out why she is always running out of zip lock bags.....
I recently found some that have a zip thing to close them and they don't cost much more than the regular ones you squeeze to seal and they are better yet. These bags come in gallon and quart size I think. I do use a magnetic tray at times but only to put the parts on when reassembling....
One side note: those pesky Gnomes can't seem to figure out how to open the bags and steal parts yet......
