Manzanita Lab offers the Chinga and Seymchan meteorites in this anomalous group.

Specimens of the Chinga (Russian Chinge) meteorite were found 1913 in the Chinga River, Tanna Tuva, Tuva Republic, Russia. Originally found by gold prospectors, recent expeditions equipped with modern metal detectors have turned up additional specimens such as these. The high nickel content (15.7 - 18%) has aided in preservation of these meteorites since they fell an estimated 2000 years ago.
Ataxites have a very fine crystal structure due to the high nickel content so Chinga meteorites are typically displayed with a polished surface and not etched.
These are outstanding display specimens of the genre.
Structural Class: Ataxite
Chemical class: Iron, ungrouped, 16.38% Nickel, 0.181 ppm Gallium, 0.082 ppm Germanium, 3.6 ppm Iridium

The Seymchan Pallasite was originally found in a brook-bed flowing into the river of Hekandue, a left tributary of the Jasachnaja River in the Magadan district, USSR in 1967, and because the specimen found had no olivine it was originally classified as a rare, IIE Iron. 
A recent expedition has recovered several more specimens including some that contain olivine crystals making this a pallasite! 
Structural Class: Coarse Octahedrite; bandwidth 2.0mm, with pallasitic portions.
Chemical Iron, ungrouped,  9.15% Nickel, 24.6 ppm Gallium, 68.3 ppm Germanium, 0.55 ppm Iridium.
