Yes, it's a sewing machine.

I had two of them, but one was broken, and I could never get along with the other one. It kept breaking the thread (probably a simple matter that a bit of cleaning and tuning would have solved, but what do I know) and recently it wouldn't even stitch. The upper thread would not go around the bobbin in the right way, so it would just come back out of the fabric again.
I just lost my patience and didn't feel like dealing with this at all. So I went and bought another one instead.
And isn't it sweet? I got it for 10 euros and it's in fine working order.
I googled the brand name ( Pinnock) and it turns out that it's Australian! The model closely resembles a picture that I found of one called the Sewqueen, so I guess that's what it is. The one I found isn't two-tone, though, so mine is prettier.

I'm not much of a seamstress, I admit; but it's very practical to be able to sew, even if you can only sew straight things like curtains and so on. I just made myself a new fleece collar to wear on the bike. I think this sturdy and sweet little green machine is going to keep me good company for quite a while.
