Thanks for all that posted thus far:
Tom - Thanks for confirming the aluminum top, This is surprising, figured they'd just use a steel top

Randy - No the cylinder isn't purple. It's just the dried gas on the inside of the cylinder combined with the flash on the camera, gives it a purple-ish look

Steve - If you think it's been cut down, I will end up getting a 10 gal cylinder for it.

Hope someone can confirm the handle. I may have to post a better pic of it.
