Those Sewmor machines are not 15 clones because of the tension on the front they are straight stitch only. The gray one has a drop in bobbin like a Singer 66 - the blue one is like a clone except for the tension on the front
When I got the gray machine it was totally brown. I keep cleaning more stuff off it all the time - I think it wants to be petted or something. It turns so well - nice machine.
