I don't know the model, it has no markings other than the Dobro logo. I think it was made in the 60's, it does not have a spider bridge. I bought it second hand before the prices started to skyrocket.

We recently bought a Dobro bass. It has the body of a wooden Dobro but with a long bass guitar neck. It's the only accoustic bass guitar I have ever heard that can cut through other instruments without being plugged in.
