Hi , i hate to be a pest but something odd happened on the antiques forum , probably nothing.Ive been trying to identify an old S&W and only today discovered where its SN is , it is apparantly a 4 digit number and has an X prefixing it.Was i unwise to put the number out on the net?Also does 4 digits have any significance , sorry to ask again but if ive made a boo boo i need to some deleting.Thanks
