I am trying to find out what model number these IH disks are so I can buy a manual. Can anyone help?

The proper name is "harrow plow". Any manual that doesn't say that will be the wrong one. The only one I know of with 7 disks was the number 2. I imagine there could have been others. It doesn't look quite like the pictures I have of a number 2. Are you sure they are IH?
 
This looks like a No1 tractor harrow plow produced from 1927 to 1931. Thats the only harrow plow i could find in my book. Hope that helps you, Erik..
 
here we know them as "tillers", to me its not a disc,or harrow or plow. dont know why they are called harrow plows? as they dont harrow but close to a plow job as they turn the soil over.maybe they should be called disc plows as its a disc plowing.?
 
Here in Kansas, they are known as a "One-way". Krause Plow was real big in them and was the first implement they built.
 
In South Dakota they were called one-ways , used mostly for grain stubble preparation as I recall or fall cultivation. Goes deeper than a regular disk but not as deep as a plow and turns the soil over less than a plow would. Why the name who knows.

A disk plow is a different machine. It generally works deeper than a harrow plow, closer to "plow depth". The two machines can be distringuished by the way the disks are attached. On a harrow plow, the disks are mounted on a common axle. On a disk plow each disk is carried separately on its own bearing.
 
(quoted from post at 19:32:19 08/05/11) They were also called disk plows a bit later

OK, I'll type slower this time so everyone can follow. As I said earlier, A disk plow is a different machine. If you look at the pictures above, you can see the differences I mentioned in my earlier post.
 
The disk plow, slang term "breaking plow" replaces the moldboard in drier climates, it does the same thing as a moldboard, i.e inverts the soil and buries the weeds. The tiller or one way, or harrow plow as Jim says (I have never heard that term or seen it in print before Jim mentioned it) amounts to 1/2 of an offset disk, which throws the soil two ways. However, the one way and the offset may have different angles of the disks. The one way (my preferred term) will uproot the weeds or stubble but usually lays them on the ground. Due to the two way action of the offset disk, the weeds are generally buried. The one way used to go deeper than the offset, but shallower than the moldboard or disk plow. One ways are no longer in production, the larger and heavier offsets probably penetrate as much as the old one way.
 
In my book they were first used in Australia around 1907. IH built the No.1 Tractor Harrow Plow from 1927 to 1931. Other models were built with the last being the No.14 in 1962.

They plowed and disked in one pass - and was followed by a seed drill to replant the field.
 
In the 1940 IH General Catalog the only 7 disk -harrow plow they list is a number 2 with 20 inch blades. In the 1920"s - 1940"s all disk, spring tooths, and drags were called disk harrow, spring tooth harrow, and peg tooth harrow, that where the term the term harrow plow comes from..I have 5 disk - harrow plow that I believe is a number 7. I also have some owners manuals for disk harrow plows.... Give me a call at 320-468-6474
 
No, I just got the manual at a tractor show. I went to a couple of plow days down here, and the disk plows were doing much better than the moldboards I am used to, so I thought I would check into them.
