Clicking on that a couple of times to make it a little bigger ......
Left to right
Top row: #1 might be a Vacor ... there _are_ older styles which look like that also, but i'm leaning Vacor. #2 needs more views. #3 ... hard to tell with the red and white swirl ... could be old, could be new. #4 is a Vacor.
Row 2: Vacor on #1. Not sure on #2. #3 could turn out to be an older marble -- an Alley -- but I suspect it is modern. More views could help. Not sure on #4 -- leaning modern.
Row 3: #1 is modern, but i'm not placing the maker right now. #2 is an old German handmade. I think a latticinio again. #3 ... not sure. #4 not sure, leaning modern.
