Looks like one side strip is missing.
At least 4 different kinds of men. Hard to tell from the picture what kind. The blue ones look like American. The red look like a mixture of Dynamo, old style Tornado and something else. The black look like possibly the pre 1980 original style and the early 80's new style before they went to a roll pin.
If you're buying this to bring up to tournament specs, you're pushing the value. If you're a true newbie and just want to get a solid table, then go for it. You'll probably always be able to get your money back on a resale, assuming it doesn't have some unseen problems.
Raise the table top and look for water/moisture damage. Take a decent ball with you and check to make sure the playfield is not bowed. Make a counter offer for it. You might get really lucky.
