the modified sight hurts the value but as an heirloom from your dad, it's priceless anyway!
Thanks for the info and the link.
So we are assuming it has been 'modified' sometime after it left S&W. I know Dad wasn't the type to do that to a firearm. "If you can't return it to stock, don't do it." ....... to guns or cars! Must have been done by the previous owner.
