mystery 20ga SXS

[savageshot]

i justsaw a 20ga SxS for $100. i don't know much about this brand of gun though. The rightbarrell enraving reads "Davidson Fire Arms, Greensboro NC." the left barrell reads :Model 83 Made in Spain Nitro Proof" The gun looks clean, it's got fixed chokes and it looks like some sabot slugs have been fired down the smoothbore. does anyone know anthing about this brand of gun? any response would be greatly appreciated.

There is a Davidson F.A. from Eiber spain but they don't list a model 83 . They do have a model 63 though .
