1937 Chrysler Royal

Hello,
I need to sell one of these too for my Aunt. It belonged to her late husband, and was parked under the lean barn in the late 70's on the farm here in Kansas. I would greatly appreciate any opinions of what a fair sale price should be. Pictures can be found here:

Thanks for looking, and I'm happy to answer any questions.
