The transverse shuttle Gritzner ( sp?) had a broken handcrank knob, the shuttle was there ( pictured underneath) but it would take a lof of oil to even free it. handwheel would free for winding, but when engaged to the rest, it was solid.
Unusual Singer is a chain stitch model. I left my # with them. I may make them an offer that is significantly lower than their asking price. Lots of slides and bobbins missing. but yes, the red eye was pretty and maybe intact.
