Just like here in North America, Siberia is a huge place and the sable differ in size depending on the section.
Sables are actually very similar to North American martens, and most weigh around 900 g - 1300 g skinned. I've heard of bigger sables, but they are very rare. A zoologist friend who has studied the sable his whole life says the biggest he's seen was around 1.8 kg. The largest sables are said to live on the Kamchatka peninsula (and they have amazing dark, thick, glossy fur). There are also very big sables to the north from where I live, in the Yamal peninsula (they tend to be very light-colored and fuzzy).
In our area (Khanty-Mansi Autonomous Okrug, a.k.a. Yugra, a region in the middle of the river Ob basin in West Siberia), sables are relatively large, light- and dull-colored (i.e. grayish rather than reddish). Their fur is less silky than in Barguzin's but the underfur is thicker and longer. They belong to the type subspecies (
M. zibellina zibellina), and the area around our village is one of the few places with aboriginal population, unaffected by the massive reintroduction program when they released dark sables from East Siberia, Yakutia and Kamchatka to repopulate areas where the sables had been wiped out or to "improve" the local population.
As for the shape of the pelts in the video, it's because of the stretchers they use, so it's not just the pleating. There used to be strict state-regulated rules (nowadays, it's just guidelines) about the size and shape of stretchers for sables of a particular "kryazh". Kryazh (an old word meaning "mountain range") is a technical term of the fur industry that is parallel to "subspecies" in zoology, but focuses on pelt properties. Around the lake Baikal, they use wide 3-part stretchers - originally, they were intended to minimize cuts on the pelt. This way, you can skin the sable with just one cut along the gums and four small cuts on the paws:

Further East (in the Far East of Russia and on Kamchatka) they use even shorter, rounder stretchers so that the final product looks like a frying pan with a tail. Here is a link to a forum with good pictures:

Here's an example of what we catch here:
