Russell I haven't seen that coach in my travels or even heard about it until today. I've been stewing on it all day & it is a very, very odd configuration. All the rear windows are filled in with metal just like a service car... yet it has a raised roof like an ambulance. Finally kicked my daughter off the computer to have a better look at it (was using the Droid phone earlier today when you posted) and there's surface rust on all the window fillers so they are metal. Superior did this on their military ambulances in the early '50's on the rear doors, but those doors were also sealed shut, door handles removed, upholstered over inside, and they left the rearmost side windows in place.
As sad as it looks it's still very interesting. Rocker panel is gone and there's quite a hole, wonder how bad it's rotted into the front door post. I'd love to check it out closer if you'd PM the location Russell. Maybe our buddy Keith can chime in on this one, he's sharp on the older coaches & over in Shelby... possibly he's seen it before or knows what it truly is. Maybe the interior could give up some clues, especially if we can find a build tag. At any rate i'd love to scope it out for the site & talk to the owner/take detailed photos.
Excellent find Russell! You & I need to have lunch sometime. Talked to Rocky this morning & we'd also like to pick your brain on the '56 Olds ambulance I dragged out of Fremont for him, have always enjoyed reading your stories too. My vote for now is an ambulance that at some point was modified with the windows filled in. Looks like it's been set up this way for years...
