No. There is no chance that gun shipped with a 2-inch barrel for several reasons. First, it is not in the right SN range (there are two and it doesn't fall into either.) Secondly, the barrel has clearly been crudely cut. The originals have a locking lug and a rounded front sight. As others have pointed out, it started life as a BSR in .38 S&W and it is technically illegal contraband. I would NOT re-stamp the SN because now you have committed a 2nd felony. I don't believe the ATF has assigned new numbers to such guns for some time but they certainly don't allow current owners to do it for themselves. This issue comes up quite often and I generally have to eventually post this letter, so...
