Yes.but...LOL. It is such a basic machine that you wouldn't need fancy parts if one did go...also Tin Lizzie is still in business and has parts. The Pfaff and Viking 18-8's are interchangeable for parts. The only part that is specific is the computer/stitch regulator, and that can be more than the machine on a lot of brands.
I have had my Tin Lizzie for over 20 years..only part I had to replace was a presser bar spring a few years ago. Most recently I replaced the wheels on my carriage, but they were 20 + years old, nothing lasts forever. I am a stickler about oiling and cleaning, that will go a long way in ensuring any machine lasts decades.
I e-mailed floyd and lizzie's when I needed new wheels..even though he didn't stock them, he was very fast to answer my questions and help me.
