Hi Kaliratbags and welcome from me (again).
I assume your passion for those particular quilts was fuelled by the collection at the American Museum in Bath. Only been once many years past now but it made an impression on me - just not quite enough to turn me into a quilter, unlike many others here as you've probably already discovered.
I had a couple of basic machines and saved up for a long time to get my own much loved Viking 6570 (the burgundy coloured one) in the latter half of the 70s. She was much loved for over 30 years until the dreaded cam stack crack appeared. Then I bought a couple of new Pfaffs (one big and flashy, the other a small mechanical). I still have both but now also have 4 Berninas from the 1980/90s which I discovered rather late on to be my dream machines.
