What you have there is not uncommon. S&W would change model numbers (the number after the "dash"), but still have older frames on hand to finish. So it is not unusual to find a new engineering change (the number after the dash) serial number that still has some characteristics from the previous version. Not really valuable or noteworthy except to collectors.
