#3, stylized logo, size No. on bottom, no pattern #, no heat ring. I can't find anything else with this particular combo of characteristics except for pg 233 of BB, top right. But the book only lists the #2, so I'm not positive that it's the same.
Where does it fit in the timeline? Would it be from the period before pattern number replaced size number (1920's?), or the period where smooth bottoms replaced heat rings (1930's?) Is there anything unusual about this, or is it common and I haven't been paying enough attention?
