I am very fond of that era , and would therefore be tempted at that price. However - the grips gotta go , and that is a bargaining lever for you.
I agree that you could easily spend $100 on period grips - I have been that route. If you want the nostalgia , go original. If you a shooter , any K frame target grips should fit , or be fittable. Magnas may fit your hand better than targets , and are readily available.

PLEASE - no rubber grips!!! Not on that nice old piece.
