Want to Buy Linhof Technika 4x5 240 cam.

I recently acquired a Linhof Technika 4x5 V. I would like to locate a cam for a 240 Symmar lens. I am not looking for a new, blank cam, but one that has been ground for a camera. I understand they are interchangeable on the V and later versions of the Technika.

Not to confuse matters but I have 3 90mm cams for a iv/v and all are unique
