I took a magnifying glass to the pics of the smoker barrels and IMO they appear to be lined.
You will never know unless you see for yourself.
Around here a new or "reconditioned" unlined open 55 gallon drum with lid and lock band run $35-50.
Locally, Stock Pot Soups will usually give away food grade drums, and I've seen both open and closed ones that were lined and unlined, some contained Olive or Canola oils, or lined open drums that held tomato puree in bladders.
At our shop, bearing grease comes packed in a bladder in lined open drums, and a local paint distributor routinely gives away smooth side open unlined drums packed with paint pigments in bladders.
