Another way to tell from a picture is if you can see the little peg in the bobbin winder - that would fit into the tube of the bobbin. There were only a few companies that had hollow bobbins, White being the most common (by a long shot). This machine looks very similar to my AG Mason (made by White). Mine does take the same bobbins, needles and attachments as the other White VS machines.

Some of the identifiers for White - hollow bobbin (and shuttle / winder with the peg) Rectangular needle plate (Davis also has this) Belt on the inside of the flywheel (Davis is usually outside).

I think White is another (along with Singer) that didn't use the top tension (leaf style).
