Can anyone help me with my Goodwill Espresso machine pickup?

So today I bought an espresso machine for $5.99 at the local Goodwill, and I can't find any info about it online. The front name says it's St. Gallen model 700. Here is a pic of what I bought, showing what it comes with and here is a picture of the tag on the bottom. I really have no idea about espresso machines to begin with, but I've been wanting to get into it for a while. I think there are some parts missing, so I'd like to find somewhere where I can buy them so I can have a full set for it. Any help you guys have would be appreciated!
