Beautiful old Regal made Dobro resonator round neck guitar made around 1930. This model is amongst the very 1st resonators produced by Regal for the Dopyera Bros.
I have been leaning toward the metal bodied ones because of what happened to my brothers - it got pretty dried out and needs a lot of work. (but it's not too far from being a decent player if we can get the neck straightened out - no truss rod though.)
