Beautiful Mystery (no longer) Blue Car

Wallpaper Description:

Okay all of you car experts, I need some help.
I know more about nature than I do about cars.  I found this beautiful automobile parked at one of my favorite nature centers. I could tell that someone had put a lot of time, work, and care into this one. I took several photos of it and kept hoping that it's owner would show up. Finally I had to give up and leave.

All I know for certain is that this car is a Chevrolet of some kind. There wasn't a year on it or anything.

I tried looking it up online when I got home. I believe this car is from the 1940s. The 1950s is also a possibility. That's all that I could figure out.

Can somebody on Desktop Nexus identify this auto for me? I would love to know what it is, and put it in a Car Group or two. If you know what kind of Chevy this is, and what year it is, please contact me by PM, on my profile, or by leaving a comment on this wallpaper. 
Thank you in advance to anyone who can help me out. I've been wondering what it is for a week now, and am almost bursting with curiosity!
