That's beautiful. My Grandparents once had a sedan version of approximately the same vintage. It was nicknamed "Black Beauty". I can't recall the year, but think it was about a '52. I do remember what the '55 through '62's looked like, but can't tell the earlier ones apart. Back then the models had names like Roadmaster, Century and some others.
Dynaflow was what they called the automatic trans. It was in use at least as late as 1960, and perhaps beyond. It has basically park, neutral, forward and reverse. I think that's the order they were in on the shift lever - reverse all the way to the right on the indicator. You didn't notice any shifting like with our current transmissions as the car went forward, it just kinda changed pitch.
I can't say I've seen one in "woody" trim before. Thanks for posting the pic................chim
