Yep, they still make 'em. Stock is now synthetic instead of wood and they are Stainless instead of Blued.
Look for a 70PSS...the older wood model is the 70P
As to where to buy, most places you can order one...
but it might be easier to find at Gallery of Guns and have one sent to your favorite local gun shop.
Or use one of the auction sites...and have it sent to your local GS.
Of course, you can also find great deals on used ones online & in pawn shops/gun shops...and in your local paper.
So if you prefer the wooden stock, they aren't very hard to find...its the case that's hard to find with a used one.
