I would be most appreciative if one of the members could give me the date of birth for an N frame with the serial number S257001, if that information is available in one of your resource books.
That information is not available. Factory letters document shipping dates, not manufacture dates. Sometimes guns sit in the warehouse for years before being shipped out, which accounts for the very wide variance in shipping dates and estimates based upon observed serial numbers. S&Ws were not shipped out by serial number order.
