Help in identifying Dura Ace components?

I'm waiting on delivery of some Dura Ace parts and am wondering if they are from different groupsets. The FD has the cut outs which look similar to those from the Dura Ace 1973 set but it doesn't look like it's that old. The RD looks like it's from a later set I'm thinking. Any information would be greatly appreciated. Thanks
