The Amiga 3500 is legit. It's a prototype A3000T, came out before the 3000T in one of C='s generic PC-style cases of the era, before they released the actual 3000T in the case people are more familiar with. They were used internally at Commodore and I don't think ever made available for public sale. When C= went bankrupt several of them "snuck out" during the ensuing chaos. There's photos of one floating around on the net that was actually used as an internal CBM email server (before the Internet as we know it). A neat piece of history!
