That is one i would not have even thought twice about - I keep hoping to stumble upon a nickel plate model. I found one in a quilt shop, but the owner wasn't there and DH didn't want me to contact her about buying it - poor thing was in horrid shape! He figured he couldn't get it running - All I wanted was the nickel plate stuff. Since it was used as a display prop, it will probably still be there if we ever get up that way again. DH was being a pain that day, and since we had just picked up a treadle machine, I didn't want to push the point.
The neat thing with these, when you change the stitch length - the number that appears in the little rectangle cutout changes. Just kind of a neat option.
BTW - as far as i know, this option was only put on the 15-91, and it is quite rare. Though not really in great demand . . .
