Welcome! I love the flying pig.
Looks like Glenn has you covered. Gorgeous cabinet and the Scarab is one of my favorite decal patterns-actually I think it is my favorite of all the ones out there, at least until you start getting into the MOP machines. Free's Peacock pattern is right in there too. The original manual is a really happy bonus as well.
It would be a shame to break that set up and I hope you decide to keep it as a sewing machine, it's well worth the effort to repair it and put it back to work.
Take a look at the stickies on cleaning these old machines, it's worth the time to watch the videos too.
If you've never sewn on a treadle before, it's surprisingly easy and it's fun!
