I'm home now. Here's a more detailed description.
It is 22.5 inches long, 13.25 inches from nut to bridge, 5 inches wide at the widest point. The body is flat top and bottom and is 1.125 inches thick. There are no markings of any kind although someone wrote GDAE inside to remind them how to tune it.
I have been in touch with Elderly but told them I don't want to sell it. They may not respond.
