Hoping to find someone who has one of these lurking around in their junk drawer or parts bin.

The rail is 7 inches wide and 3/4 inch thick with the 1/4 inch wide rack gears being located 3/8ths of an inch inward from the outside of the rails.
Locator pins are located 1 and 3/8ths of an inch inward from the outside of the rail. Please see photo below for physical layout.

Will consider any condition, but hope for complete example.

Thank you!

There's a "mystery rail" ad on the third page of the large format forum FS ads, maybe it might work?

I have one, but it's attached to the rest of the camera.

It would not be hard to make, except for the brass tracks.

I'll check it out; thanks!

That's the general problem! :smile:

If I cannot locate a vintage rail, I will probably just make an adapter plate that moves the tripod screw to the middle of the front rail. I have 14 inches of bellows draw already, it's just awkward to have all that mass hanging off the front rail when mounted on the original tripod mount.
 
I feel like gear tracks are a pretty standard thing in standard sizes, so should not be too hard to find. McMaster Carr has them. Measure carefully the size & spacing. The brass locating pins should be super easy, a length of brass rod cut to size, and deburred.
