Welcome to the Quilting Board!
congrats-pretty machine and pretty table too..i have a "free" that was made sometime in the first decade of 1900...and it works like a charm. it came to me for $65.00 and included all of the attachments, the original oil can and the original book (very fragile but readable). they are easy to care for as long as you remember to oil, oil, oil. 15/1 needles do just fine. i hope that you use your attachments..the hemmers are fantastic. westinghouse bought out the free company and if you read the history of these machines you will find that brother is the current company..the history and the patent application process is fascinating history of these machines.
Update: Stella is oiled and I used her last night. Going through her to oil, she is actually really clean and in very good shape for her age.
The threading was a little tricky. I was putting the thread through the needle from right to left. She would not make a stitch and the thread kept coming out. I checked everything: feed dogs, overall threading, bobbin, tension, the needle, etc. Finally as a last ditch effort I put thread into the needle from left to right and it worked! Funny how one little thing like that made such a big difference.
Anyway - she makes a really nice stitch. I figured out adjusting the stitch length, and going backwards to lock the stitch. The tension is better than on my 'modern' (but cheap) machine. Stella is a bit (ok, a lot) noisy, but we think the motor is loose. DH is going to try to find a way to tighten that up.
Ey, I've found yet another sewing addiction.
