Thanks Macybaby and SteveH for the info.
If anyone has a purpose for the two clippy thingies on the bottom left, I'd be happy to pass them on for free.
Hmm, I think perhaps I might try playing with that foot on the upper left and my new mini torch to see if perhaps I can turn it into this blind stitchery foot that I've been eying and just can't bring myself to spend that much mulalah...
