How far back can we accurately plot the value of US stocks?

Like, if I wanted to see the price fluctuations over time of Wright Company of Orville and Wilbur Wright fame is there a website I could view it on? A 10 minute google didnt provide me any answers so I'm curious if anyone has looked into things like this or if I'll need to contact the Library of Congress to see something over 100 years old because it isn't digitized? Or does that data not exist any more for some reason? Did it not even get recorded?
