The 1st gen. does not have the letters down the back like this one. It just has the word Rally down the body. Don't know where to get a photo of it however.
The illustration above is from the 1976 Campagnolo catalog No. 17a, but the 1974 catalog No. 17 shows the same derailleur as catalog 17a, with the same pivot bolt (p/n 3456). I'm not sure when the Rally RD came out, but the previous catalog (catalog 16, 1968) does not have a Rally RD in it.
A later Rally RD is shown in the 1986 catalog, and it does use a different pivot bolt, p/n 3506.
