You can't tell if they are complete unless you open them up and look. the M1959 basic unit is just a big box (what you can see) that opens up on the front to reveal a nested 20 and 15 gallon stock pots (with lids). Top flips up to reveal a square pan about five inches deep used for deep frying, etc. that also has a rack in it for holding Mermite inserts for warming/serving. Loaded into the deep square pan will be a griddle, stacked on top of the griddle should be a collection of knives, spoons, ladles, potatoe pealers, measuring cups/spoons, cutting board, and other utensils. Unit has a gas (regular or unleaded) burner that slides into the very bottom. I have not seen one up for sale at GL in the last couple of years that had the burner in it... The M2 burner can be converted to run on propane (guy at Seabee Cook dot com has a writeup on this), or you can rig up a high pressure burner assembly to slide into the rack in place of the gas burner (much safer and easier on the wallet). I have two of them... They were used not only in the mobile kitchen trailers but as stand alone units. Each one has the utensils and tools needed to cook food for 150 troops (not included the troop's individual mess gear, sanitation gear, etc. that was also shipped with the kitchen trailer or otherwise supplied when setting up a mess unit...
Unless it is wrapped up in a big plastic wrapper with a not saying that it is "new", assume that it is missing a few items...
They are great if you cook for a group even though they are heavy...
