Buying used kegs from Northern Brewer

Hey everyone, I am going to purchase some used 5 gal. kegs from Northern Brewer in a few minutes, I was wondering if the kegs I will recieve will be "Cornelius" kegs, or some other similar brand... I need to know as I plan on purchasing some Corney-specific parts such as poppets and maybe a spare keg post or 2 In the same order. If I bought the corney poppets and posts, and then ended up with some "firestone VI" kegs at my door I'd be kinda screwed...

Thanks for all the help!

Shouldn't you contact Norther Brewer about that?

lol, what he said!
