Blaser still makes the R8's predacesor, the R-93. Its slightly lighter and sleeker, but can only handle calibers up to .416 Rem. Mag. The R8 can go up to .500 Jeffery.
Before that there was a Blaser "Ultimate" and an R84 I think.
In early straight pulls there is also the early military Steyr, the U.S. Navy 6mm Lee, and several models of Schmitt Reuben used by the Swiss for many decades.
I have a matched pair of R93 Professionals with 9 barrels that is the backbone of my "retirement battery" so I'm biased.
