It's going to be (my guess, and we KNOW what that's worth...don't run to the bank with it!!! ;) ) either a 27, 127, 28 or 128...hard to tell from the photo they show of the machine, and cutting off the faceplate in the photo.
Pretty machine...I'd make them an offer...ask about attachments, extra bobbins or shuttles, motor, etc.

It doesn't necessarily need a cabinet to work, it depends on whether or not it's in a case...

I agree, if it was the whole machine in the picture you could tell what machine it is. I think it is a shuttle bobbin machine....
As long as it comes with the knee lever and the top of case and key....I would make an offer...she is very pretty.

Thank you all so much for taking the time to answer my post. I am waiting on a reply from the seller, I will let you know what the outcome is.

Oh. what does a shuttle look like? Any links?

Here you go:

Oh no scary!!!!

Heh! Not so much...and once you actually do it, it's kind of fun! :)

They're wonderful to sew with. Some people prefer FMQ with them over their model 15's. I keep meaning to try it someday, but my 27/28 models are buried in the garage at the moment and I've gotten attached to that big class 15 bobbin that I can replace even with a quilt on the machine.

But, I've pieced quilts with the 27/28's. And my little 128 treadle has a picot/hemstitching attachment that produces such a beautiful effect on linen - much easier to control than the 15. That amount of control is great for free-motion embroidery, too - you can sew just a stitch or two, reposition the fabric, couple more stitches, reposition, etc. :)

sometimes refered to as a bullet bobbin...

Hello everyone, just thought that you would like to know that I still haven't heard from the seller. But I just posted another find here is the link:
