I have one; from the 40s I guess. They are great, funky blues & old-time guitars. Regal made them for B&D who were banjo makers. Be warned, though, the necks are very, very large V-shape. I don't play mine much--I use a Recording King when I need to play a 16" jumbo. The neck on the RK is slightly better for me.
I'm in middle Tennessee; if you're in the area you're welcome to come play--see what you think.
