One gun with 12, 20 and 28 gauge barrels??
 

So the listing says...

Beautiful wood on this one!

Looks like three guns; one in each gauge, all two barrel sets and all three for one big price?

It appears to be three separate 2-bbl. sets being sold as a "set", no?

Ah.. That makes quite a bit more sense, when I saw, "all 3 sets same low serial number, I thought he was referring to a set of barrels". Not much detail in the ad, and only one picture...
