FA*300/2.8 and FA*600/4
Could be a scam also so beware. I used to cruise ebay reporting astronomical gear scams for several years for them and using someone elses photo in your listing is one of the favorite ways to try and do a fraudulent sale.
I thought about that, too, Kent. Both lenses are available ONLY from sellers in East Asia (Japan, China, Korea). Both lenses are also at what I'd consider CLOSE to a FULL MSRP for a NEW lens of that category, based on what Nikon/Canon/Sigma get for similar lenses (Sigma's price for a BRAND NEW 300 F 2.8 lens is, for example, about the exact same as the asking price for the lens on ebay, and I'm pretty sure the Sigma lens comes with a 4-year warranty).
A word is worth 1/1000th of a picture... Maybe that's why I use so many words!
