Good buy
I've had mine since 86 or so, it is part of the family; my kids all learned on it, grandchildren will be very soon too. I took a couple inches off the stock.
I lost a dear friend and mentor in 2009; he was a damn fine man so I took a liking to him. After he died, I cleaned his model 60 for him, it was a lot older than mine. Point: I didn't see a whole lot of difference between the two rifles.
The trigger guard, the buffer, front sight, the magazine plunger and one take-down pin had gone from metal to plastic.
I don't emagine the basic design will ever change.
Good choice.
