The Slovak, Arkansas, H5 chondrite also shows such large metal nodules. Cp. D.W.G. Sears' booklet Thunderstones:
1) B-W photo, p. 21,: Figure 8. Photograph of two cut and polished faces of the Slovak meteorite showing the LARGE METAL NODULES present in this meteorite. It is widely assumed that an impact in space caused the small metal grains to coalesce into large nodules.
2) Text passage, pp. 61-62: As a rule, the H chondrites are less heavily shocked than the L chondrites, but many of them are black, and the Slovak meteorite contains large nodules of metal which are commonly regarded as the result of shock.
3) My 40.5 gram Slovak specimen (dimensions: 6.0 x 3.7 x 0.5 cm) shows one elongate inclusion approximately 14 mm by 5 mm with troilite intergrowths. This inclusion doesn't show through to the other side, either. One of the cut and polished 0.5 cm surfaces shows another nodule (0.6 x 0.3 cm) 'in profile'. It doesn't extend to the other side, either. Instead, this nodule stops short of reaching the other side. There is a third almost circular (0.7 x 0.5) nodule close to one crusted edge, and here again, no sign of showing through. There's a fourth, small patch on the rear side which might belong to the large elongated inclusion mentioned above. By the way, the large elongated inclusion is the only one that harbors troilite 'bands'. The other inclusions are free from troilite.

(Meteoritics 32-1, 1997, pp. 19-24):
Abstract - The Leedey, Oklahoma meteorite shower fell on Nov. 25, 1943,
following a fireball which was visible across much of southwestern Oklahoma
and northcentral Texas. The shower produced 24 stones with a total mass
of ~51.5 kg. The stones formed a strewnfield ~18 km in length in the same
direction as the observed path of the meteor (N50 °W). Leedey is classified
as an L6(S3) ordinary chondrite. We report bulk major element chemical
analyses from four separate laboratories. Leedey contains an unusual
6 by 8 mm composite Fe,Ni-FeS grain, which is composed of a 3 mm kamacite
grain adjacent to a 5 mm troilite grain. A 50-100 µm rim of high-Ni
(45-55 wt.%) taenite (tetrataenite) occurs at the boundary between kamacite
and troilite. A single, zoned pyrophanite grain is observed at the boundary
between the inclusion troilite and host silicates. An origin as a foreign
particle incorporated after metamorphism or during impact melting appears
unlikely. This particle likely formed by a complex set of processes,
including melting in the nebula, parent body metamorphism and reheating
by later shock, mirroring the history of the host chondrite.
