Sheaf Fork

I would deny being a tool geek but I do like old tools, know a bit about them and am constantly amazed by the ingenuity of folk  who worked by hand in designing efficient tools for specific jobs.
This is a sheaf fork.  Once your wheat is cut and lying beautifully straight in it’s windrows then making sheaves is just a matter of scooping it up with the fork so it collects in front of the two little fingers.  Job done, all you need is a band to tie it up.
Simple, effective &  brilliant. Where can I get one?
