Very nice machine! I'd love to use one, and if I had lots of room own one. I remember reading somewhere that Phoenix was a German company, but don't quote me on that.
That is the mose unique bobbin case I have ever seen. Sorta trapizoidal. I'll have to dig out my iPad and see if I can find video of it in action (my desk top doesn't play video.)
Thank you for sharing! Glad you got it working, I'm sure you or someone else will treasure it for years to come.
