Those are warne, not talley and they are mounted on weaver style bases. They are also warne maxima series which are made of sintered steel, unlike the original warne premier series that were machined from solid steel. Warne made both series to fit sako's tapered dovetail at one time but both have since been dropped.
I really liked the premier series warne, but since they are no longer an option the 1-piece ringmounts from sako are quickly gaining favour. I refuse to add bases to a rifle with integral bases so that limits most options. Basically you have the ringmounts, leupold and millet. Leupolds are alright, but aren't in the same class as the ringmounts. They aren't as strong, their stainless mounts aren't stainless but rather plated, and now leupold puts a big cheesy "L" on the tops of the rings which is hideous. They have 3 pluses. They are easy to find, are slightly lighter, and cost less. I recently bought two sets, and really wish I hadn't but rather spent the money on the ringmounts from day one. The ringmounts can be had in actual stainless steel. Have a recoil stop pin, 4 screws per ring top, and 2 much larger clamp screws - plus the nylon inserts which correct any misalignments, and won't mark your scope tube. Some guys complain they have soft screws but in the (at least 10) sets i have used I have never had an issue. Use a proper fitting wrench and proper torque and you shouldnt have an issue. The latest version uses torx screws which are better yet.
I won't even speak of millet.
Below is a picture of the 3 I mentioned. Warne premier series fixed mount (in silver - not true stainless) leupold matte and stainless ringmounts in 30mm
