I prefer the earlier gun. As Raimey mentions the Cabelas gun (serial number #47) is an early hammerless most likely made by Georg Lindner. I own a very similar gun (#7) and it has 2 and 7/8" chambers. As Pete mentions, #47 features highest quality damascus tubes and beautiful wood. It looks to be a very tidy example.
The Bob Jones gun is a later gun. I would be shocked if it were not made by H.A. Lindner and should bear his marks. It is SD&G base model at the time - the model 118 (note the dollshead extension and lack of ejectors). Given the fluid steel barrels (should by Krupp) and lack of sideclips this is likely a late 1890s - very early 1900 gun. That said, the gun has been redone and has a lot of drop in the stock.
Both guns would make additions, but I find the older gun more interesting and desireable.
