Firestone sign

This morning I had nothin to do so I decided to go for a walk. I ended up walking on these railroad tracks that aren't used anymore with is where I found this sign. I was their only 3 days ago and I didn't see it then so I think someone found it started carrying it back but got tired and was going to come back for it. So I finished the job for them. It looked like the whole inner body of it was painted a burgundy color and the top and bottom rocker/handle things were a cream color according to other pictures I found of it. I don't know much about it except that I think it's from 1948 because it had on the bottom right side it said MCA 48 there was something between the MCA and the 48 but it was to rusted to read. It's about 5'6 5'7 wide and about 2'5 tall. I'm 15 and my name is Matt I don't really know how much these cost so if anybody could tell me what they would buy it for or what they think its worth it would be greatly appreciated. (I probally would not sell it anyways because its just to cool)
