The 19 is more pointed and is similar to say the EG 82, where as the 48 is more soft square - perhaps somewhere between a 202 and 606.

I think if the Chestnut Adelaide had been photographed straight on you could more readily see the difference in the lasts. The difference is subtle, but not as subtle as the photography is making it look.
Yup, you're probably right about the angle of the pics because there sure is a difference in the last comparison pic.
