Hello Wendy - glad we got there!
Why don't you put a photo on the Vintage Sewing Machine Shop Photos thread? I think the fact that it has the same insides as a 99K is fascinating, and something worth explaining on that thread! You can see my 1916 99K at
http://www.quiltingboard.com/t-130994-10.htm - it has the old fashioned screw for the stitch length instead of a lever - and smile at the fact that you are looking at essentially the same machine. Have you taken the face plate off yet and seen the works in motion? When the needlebar moves the mechanism it is attached to looks like a performing monkey... you'll know what I mean when you see it.
