Yes that's elephant trunc stew in njemboué sauce (oil palm sauce).
I tried that dish in 2003 when I visited Gabon in equatorial Africa. I can not say that it was something that I would retry anytime soon. The taste was not so bad, but the texture was quite unpleasant, chewy like oversized tripe or squid rings.
