The second machine is definitely different, it's a model 99. And the different backdrops should clue you in that one of the photos is lifted. I've found some Craigslist sellers will lift photos from another person, because they cannot tell the difference between models and actually think they are the same machine. In this way I was fooled into pursuing a Craigslist lead, thinking I was going to be able to purchase a 31-15 treadle. But the seller had used a photo lifted from somewhere else, and though she insisted the machine in the photo was identical, what she had was a model 95 with an industrial motor.
