hand powered threshing machine
 

I have a hand powered threshing machine, my grandfather has put it
togther as best has he can and now I have it. And I would like to put
it back the way it should be . The problem is that I have not found
any pictures of a orginal to go off of and one piece the lid is
missing and I think that is the part with the patent number on it. So
if anyone can point me in the right way would be great.
Thank you
