Grain drill info?????

I have been looking to buy a Oliver grain drill for the past few months, I want to use it to plant soybeans and small grains for deer food plots. I have found a few for sale a few hours away, they do not seem to be common in my area. I would like to find a 8ft or 10ft wide planting width. I want to keep it on the narrower side due to some tight areas/fields I have to get to. Anyway the one I am thinking about going to look at and possibly buy is a 8.5' width just what I am looking for! I believe it to be a model #64 {no serial number yet} with rubber tires and I think it is a trip style not a hydraulic lift. It has what appears to be three different compartment/boxes, I assume: 1 front box for seed, 1 middle box for fertilizer, and 1 for grass seed this being the smallest of all and on the rear of the drill??? The drill looks to be in ok shape but definitely needs some TLC, the price is definitely in my budget even if I need to spend some on getting it field ready. How available are parts for these drills? In the 2nd box, the one I believe to be for fertilizer there seems to be something missing from the pictures I got of it. The gear looking plates that sit on the bottom of the box and appear to turn are all missing. I think they turn and when the notch part goes over the hole in the box it lets the fertilizer drop in the tube? I do not plan on using the drill for fertilizer, so I may not even need those parts. My other questions are does the trip style lift/drop for these drills work ok? Or should I just look for one with a hydraulic lift cylinder? The tractor I will be using to pull it does have remotes so I can run a external cylinder. What size tires are usually on these drills? The tires look pretty rough so I will have to come up with some rubber for it. I have never actually used a grain drill before so I am just trying to get all the info I can before I make a purchase. I do think I understand the basics of how a grain drill works and that it needs to be calibrated for the type of seed you are planting etc. Thanks in advance to anyone who replies. Also if anyone has one for sale or knows of any for sale in the NY, PA, areas let me know please.

Not exactly what you're looking for and nowhere near you, but this is a good deal and in great condition for its age.
