I think Bigduke6 is just showing us his vickers chest with his lathe attachments in it. The vickers chests aren't throw aways, as anyone with a vickers must have this chest and the main storage chest. But I doubt it will be worth what the ebay chest is going to go for; currently at $526 with a day and a half to go.
The one thing that confuses me is the NSN on bigduke6's box. The stock class and the country code are ones I am not familiar with. Usually weapons stuff is 1005 stock class and Britain is a 99 identifier code. Can't say as I have ever seen "0120-90- as is on his chest.
By the way, I could use that tripod box, but it would just join the rest of the stowage boxes on the pile. I keep accumulating them, but have quit storing them in the gun room.
Here is just the Cno7 pile:
