Thank you everyone for all the wonderful information!!
I haven't sewn on her yet, so I'll have to see how that goes.
I learned to sew on my grandmother's treadle Singer, so it's automatic for me to hold the thread tails, even when it's "supposedly" not necessary on the newer machines.
She's black, and her emblems are in pretty nice shape, not a lot of wear on them. I'm at work right now, so it will have to wait until this evening to start doing more research.
The previous owner had said she just had it serviced, so we'll see how that goes. Neat thing is, I found her on Facebook's "Marketplace"... and because of the really nice conversations I had with the previous owner, I now have a new customer for my longarm business, even though she's a couple of states away!
She's sending a "Christmas Baltimore Album" for me to custom quilt for her!
I'm really excited - both about my new toy and about my new customer!!
Thank you again, everyone, for all the wonderful information. I've pretty much quit asking my questions about quilting stuff anywhere else but here!!
