My 1st antique I acquired is a Singer 66, treadle that has been converted as well. It's in the original cabinet. It was my great grandma's (Ma), passed to my grandma (Nanny). My Mom never has liked sewing, so lucky me got it!
I had many a wonderful summer day laying on Ma's bed watching her sew clothes for all of us.
Here's a link to some pics I posted here a while back, in the pic you can't see it, but it does have an electric motor on the back of it:

I also found a Minnesota Rotary in the cabinet for $15 on CL, works great. Hadn't heard of that brand either.
And I have 2 featherweights. One is from Great Britain, the other I just acquired.
