after the question about lens boards, I have a similar one for bellows : being building the view camera from Jon Grepstad's design, I'd like to use a used bellows to avoid making my own.

I know from the building documentation that a Cambo bellows has panels of 162X162 mm. My issue is I found one used Cambo bellows but it's 108, and that makes a big difference in my budget. As I saw some Sinar and Toyo bellows for half that price, I wonder if I can adapt them.

So I'd be happy to know what are the frame sizes of Toyo and Sinar bellows.

Thanks for your input
