Fourtrak Workshop manual for sale - value?

Forum: 

I have a Fourtrak factory workshop service manual for sale. "F70, F75, F77 Service manual"

In immaculate (unused condition as far as I can see).

What would be a fair value to offer for sale here please?

It is a hefty tome so wou;d also cost a fiver or so to post, I would think.

Thanks in advance. Terry
