I found two tripods up for bid a Linhof with a Linhof ball head and a Sinar that is much larger and heavier. Just wonder what these might be worth. I am not sure what models these might be but they seem to be sturdy and all locks seem to work ok. Thinking these would be a good support for 4x5
Considering you have given us no useful information about the tripods for us to go off of nobody will be able to properly answer your questions.
