Box-shaped electric resonator mandolin

Wonder what the body's made of? Looks like plastic or carbon fibre?

Looks like a storage box from a container store. :)

Meant to be the steampunk version of an electric mando?

I think Jim is right. :)

If Bo Diddley played mandolin . . .

I think that "resonator" has a plumbing-supplies pedigree...
