I just bought a little 3 point disc manufactured by Industrial Scientific Compnany, Fresno, Calif (Indusco). Long since gone out of business. It's an offset disc with six blades on each gang --- set up now to be about 57" wide but can be adjusted narrower. The name plate is nicely intact. It's a model 201. If you do an internet search you can easily find some great pics so I won't try to post any here for that reason --- mine have got to be worse.

Beyond the great pics there doesn't seem to be any other info available. Does anyone know where I might be able to get an owners manual or a set up manual or any other info?? My biggest question is: What size were the original disc blades?

Don't know where you'd get a manual. As for the disc size, I'd say most likely 16". Possibly 18 but that may be pushing it depending on your tractor.
