possibly 32" barrels made in Italy........some were made and fitted to model 21's also. Never have seen a 23 with 32" barrels in all the gun shows and literature I've looked at. I doubt seriously if they are factory. The 23 came along during the time shorter barrels were all the rage...most were 26" with some 28" and like Obi Wan Skeetx said, the duck model was the only one with 30" barrels. You might pose your question to Dawson's Doubles in San Antonio and James Wayne in Victoria Tx. both dealers handle a lot of 23's.
