Vintage No-Name Tenor Banjo Stromberg?

We have a mystery tenor banjo in our store. Our guess is that it is a 1920s-1930s Stromberg because of the single bolt holding the resonator on the back and the headstock design. The tailpiece is broken and the binding around the resonator is chipped and cracked. The hoop that holds down the head has some oxidation. It would need a new nut but otherwise it appears to be all there. It would be a good project for someone to fix up. Thanks.
