I'm not sure what you are saying... I am pretty sure that the extractors are symmetric, and what differentiates a LH vs. RH is the placement/timing of the extractor groove cutout on the bolt face.
===============
Yes, the bevel on corner of the extractor will vary for a rt and lt hand bolt. At least it did for me...I had a similar problem with a custom action and the brass dropping in the port It was driving me crazy, but after a while finally realized my left hand bolt had a rt hand extractor (by comparing a left and right bolt).
Swapped it out and never a single issue since then. I can not tell from your picture as I think the bolt is rotated and my bolt is even stranger with left bolt, right eject.
Worth asking Stiller the question...
Good Luck.

A standard, stock Sako extractor has no bevel in it, and is 100% symmetric; therefor it is the same for a LH and RH bolt. The extractor in my bolt doesn't have any bevel in the claw and that it why it is ejected the brass at a high angle.
But yes, you are partly correct, if you are going to bevel the extractor claw to lower the ejection angle, the bevel will be on different sides of the claw for a RH or LH bolt.
