Sorry if this is the wrong place to post the question. I have a millet front sight in orange for the Ruger Police & Speed Six. It is still sealed in it's original packaging but the box has seen better days. It has never been mounted on a pistol as far as I can tell. I heard these are highly coveted by Ruger and S&W revolver enthusiasts and it's easy to see why considering how bright the thing still is after over 50 years. I want to find it a good home but I can't find any indication of it's worth. Would appreciate any help. Thanks!
