Our English speaking friends across the Pond tried their best to confuse us Yanks with the numbering system for the 700 series guns, which appeared shortly after the end of WWII. The base model was the 700. The next step up was the 702. And the 701 was the top of the line. I've never owned a 701. However, I have owned a couple 720s. The 720, like the 728 mentioned above, is basically a 702 made in the specific gauge (20) for the US market. 3" chambers in the 720, on a gun that will weigh less than 6 pounds. And, as also mentioned, the 720 and 728 came with the shorter barrels then more in fashion, but somewhat less so now. The wood will obviously vary somewhat from gun to gun. But the 720s I owned did have very nice wood. I believe that a nice canvas covered hard case was also part of the 720/728 package. Nice guns for the money. One way to tell a 720 (or 728) from a standard 702 is by the serial number, which began with the model number: 720xxx, for example. And there was also a 712. According to the Scott book by Crawford and Whatley, 225 712s were made; 229 720s; and 215 728s.
