Factory Target models also tended to have the Deluxe Factory Checked Walnut Stocks ( rather then the Black Hard Rubber Service Stocks ) but, of course, someone might have changed the Stocks along the way, too.
I am not confident this is even a Factory Target Model at all actually, and, without being able to see the Top Strap, it is hard for me to say for sure one way or another.
Now and then one does see New Services, to which someone has done some modifications along the way, adding an adjustable Rear Sight and ditto Front Sight, and, these ( unless maybe done by 'KING' or something ) are of course not as appealing or as valuable, as a plain old usual non Target one which has remained Original.
