Beline 1816 applicator question

[jka300]

I was wondering if anyone owns a beline 1816 seed applicator? We went to a JD dealer today to look at a used beline 1816 seeder that mounts on a cultivator, the salesman told us that all the peices were there but it was missing (I think ) 2 motors that drive the rollers and also the wiring harness and operators manual. I really need someones help since I tried looking for it everywhere on the internet. I just want an idea what its missing so I can see if its worth my wild to buy.
The picture isn't the model that I'm looking at its just to show what a beline applicator looks like
