Annette - it's just the penguin foot (walking presser foot) - the rest probably would sell for $25 - for ALL of it. If you want to buy Singer attachments with plans to resell at a profit, you need to know which are the rare ones and which are the ones that sold with every machine.
This is a good "list" though I'd add a few more (guide foot, tube trimmer, machine pinker for a few of them)
