It looks like a 221 to me too, but I can't really see the front part of the machine. If it folds up, then it is a 221.
I believe the case is one that someone has removed all the black leather or vinyl from it. You can sand those down, stain and revarnish with polurethane and it will be gorgeous.
The FW 222 free arm machines are usually around $1000 and up. The 221 machines you can find for around $200-$300 now. You will love using this! They're great for workshops and retreats!
