I'ts a K - and yes - a 99 in new clothing - except that this one is about 50 years younger than the one she wants to keep Hers is in a nice, old bentwood case. It has the old style bobbin winder and the stitch length knob with no reverse. I think she loves the look of the black one, and also knowing it's age.
One of my favorite machines is my late model 99k with the double slot stitch plate with reveres. That one really is just like this 185K in a different dress.
