Onalee... Needlebar information just refers to the machine as a "lowbed" saying that the numbering system of these early models was somewhat unreliable... for example, what started as a W&W #5 later became a "W&W #something else"
From what I can see, this is from at least the early 1870's, maybe earlier...and will be a curved needle machine. I'd be interested to see better pics of the machine!!
