That looks like it reads Star View, which was one of the first manufacturers of C-band antennas, going back to at least 1980-81. A dead giveaway is the original LNA, which from a distance appears to be an Avantek. Wholesale on those devices was over $700 in 1982. It is likely that the original purchaser probably spent over five grand on the system (without knowing what receiver was inside). Star View was either in Pocahontas, Arkansas or across the border in Southeastern Missouri. Stringing the reflector to check parabolic accuracy would be first on the list of things to do before spending money.
Early parabolic dishes such as this were built before much Ku-band activity, so it is unlikely you will have great results on that band. The prehistoric LNA and feed holder was designed for C-band, and 40 years later may be less than centered, plus the need to confirm accuracy of the reflector. You would be replacing the LNA and feed with some LNBF device, and some modifications will likely be needed to confirm the focal point. Once you have connected a live signal to a FTA receiver and checked performance on several satellites, you would then want to consider spending money on a new motor drive and positioner control. These were massive overkill systems that performed adequately in the early 80s, but the above areas (reflector accuracy, feedhorn and LNB replacement, and motor drive) will need to be checked and probably replaced. It is a heavy dish, so a massive amount of cement and effort would be needed to properly reinstall in another location. It might be productive to test things with new components in present location before disassembling---just to see if it works satisfactorily as is. Not something for a novice that does not have a local expert to consult...and you may have lots of questions for them and/or forums such as this. Be prepared to spend a lot of time from start to finish. Good luck!
