Thanks for all your help Ken. I'm a slow tech-no learner but wanted to share a few more photos of my big mystery bass (although, some things are becoming more clear). The measurements I sent a few posts ago are from this bass not the Seitz bass I posted a while ago. I've set up a link with the photos of the bass giving more detail. Any observations are appreciated. I also have a Morelli bass dated from 1910 that I'm going to take some photos of. Though I've seen a lot of Morelli basses, I've not seen too many with the same general shape as mine. Most I've seen are from the 1920s and beyond but I've not see another one like mine from 1910. Here's the link
