Need Help, What Is It!

[jpalex]

I want to thank you all again for all the help sent my way on what turned out to be a cheese cutter.
Now, I must drag out of the barn my next what is it. This was passed down to me from a contractor who lived well into the his late eighties. He was a general contractor, had a wide knowledge of just about all aspects of commercial and residential building.
I believe this is some sort of clamp of use I know not. The length is 57", each piece of wood is 3-1/4"x1-1/4". The holes in the one piece are 1-1/16"diameter, go all the way threw, spaced 7-5/8" apart. The holes in matching piece are wide enough for the 1/2" bolts to go threw and clamp down. The iron rectangle plates are 3"x1-7/8" with a 1-1/4" curved notch going into them. The wood appears to be a fairly hard wood. I have a number of plans for what I could turn this into, however would like to know what it is prior to repurposing.
Any ideas???

Obviously for a job where repeated closure and opening is necessary, so that the two parts can be disassembled without taking the bolts out each time. Would the object (s) to be held also require to have 1 1/16" holes at 7 5/8" centres... If it just held the edge of the object, there would be no need to take it apart each time...

As it is from a farm, I'd look at farm machinerey tools that need some sort of sheet material about 57" wide - the feed belt/sheet on a reaper binder comes to mind, but would you want to make such large holes in it (not even for joining it into a continuous belt)

i think its from a fence stretcher or making machine.
