Oh man, don't you wish it could talk and tell you her life story!! Good luck with your project. I've been through a couple that start out not even this good. Welcome to Stovebolt and just don't give up. She is beautiful! By the way, my 51 had vent windows, but my 50 does not. So she could be a 51 but the doorhandles tell the rest of the story. I think it looks like push button handle so I am thinking a 53. Let us know when you find out. I am courious. ;-)
