This set of HERRETT Target Stocks appears to be in New/Unused condition and will fit your S&W Square Butt N-Frame
I would say they would fit a medium/large hand comfortably.....my hand is on the larger size and they fit me well.
The photos show the stocks on my Highway Patrolman for example.
Price is only $95 Shipped (Will give this a few days before moving to the Bullseye forum)
Friends Family PayPal, ZELLE, USPS Money Order or Bank Cashiers Check for payment.
