I went back to this store today and they still have about three Detective Specials and around a dozen Cobras available, all for around $300-$350.
This is a link to their Georgia location and are representative of the quality of the pistols. A few were a lot better and there's one Cobra that's in really good shape. Serial number comes back to 1973.
And I've got a $100 gift card.......
