I have an Eldredge Two Spools in a parlor cabinet with a treadle pedal that looks like yours, the feet. My cabinet is in much better shape. As Charlee stated, most likely made around 1913.
Welcome to the Quilting Board.
I noticed that this is your first posting on the quilting board and that you didn't give an introduction about yourself.
Do you own other vintage sewing machines?
The Two Spools sewing machine is a wonderful machine to use for quilt piecing.
Do you quilt? Some of us here love using our vintage treadles for sewing and quilting. A couple of us own and use our Two Spool machines for piecing our quilts. The sewing machine foot on this machine is the perfect 1/4 inch foot. The feed dogs are equal length; so, the fabric feeds through straight. This all makes for easy piecing.
