I believe this is what you're referring to Andrew http://www.therpf.com/showthread.php?t=264616

 

US buyers you can pick up all the same components from Colemans Military surplus for under $100, and save on the shipping

Long time lurker first time poster. I'm also a frequent Coleman's shopper. I wanted to point out a few things. For one, you can save 15% on Coleman's right now using the code CA15. That offer expires August 19th so I would suggest ordering before then. Also like ukswarth points out I'm pretty sure you can find everything you need for this on Colemans.com...  They are even listing this as a Star Wars related product in their description on the page, so someone must have tipped them off! https://colemans.com/shop/containers/norwegian-military-waterproof-airtight-storage-box/
