identifying old basses

[Dwight McCartney]

Hi all,
I enjoy reading about all the great old basses around. American school, Italian, German, etc. I rarely get to see these grand old basses up close. While there have been many photos on various threads here and on TB, my untrained eye does not know what to look for.
I have read that you look to the scroll, sides, ff holes, finish and perhaps other clues when examining an old bass for pedigree.
To start with scrolls, would it be possible to post side by side comparison photos of
A: a few scrolls from the same maker or school
B: a few scrolls from a different maker or school
Possibly some commentary what to look for in the photos. Some indicators may be obvious, but some may not.
I know that is asking a lot of work, partly since it may be hard to get photos of multiple basses by the same maker, but I believe it would be helpful to learning more about this lovely instrument.

Or… is there a thread that covers this somewhere that I missed?
Thanks
