Largest LF camera mfg.?

I'm doing some market research for a large format accessory product, and was won dering if anyone had any hard facts about the following: Who is the largest man ufacturer of LF cameras in the U.S., and in the world? I suspect the answer to the former may be Wisner and the latter may be Sinar or perhaps Linhof, but I th ought someone may actually have some hard data.

Thanks,

I would say that Calumet is in there some place. But, I don't really have data on this.

Probably the maker of most of Calumet's Cameras: Cambo which is now owned by Calumet. Sinar, Linhof and Toyo would also figure prominently too, as would Arca Swiss, Wisner, Horseman and Canham.

Cambo and Toyo are the largest worldwide.

Linhof, Sinar, Toyo, Wista and Cambo are all considerbly larger then any US manufacturer.
