James Dunlop probably NGC 2136 = D 160 on 24 Sep 1826 and described "a small round pretty well defined nebula." He made 2 observations and his position is 8.6' too far SW (typical error).

JH attributed Dunlop with the discovery and recorded the cluster on 4 sweeps. His first observation of h2992 reads "pB, R, bM, 1'; has a star 10.11th mag N.p. (thick haze)." On his last sweep he noted "Globular cluster, pB, R, gmbM, resolved, stars 14..16 mag; has a vvF neb N.f [NGC 2137]."

600/800mm - 30" (10/13/15 - OzSky): at 394x; extremely bright LMC cluster, large, very mottled and lively, relatively large bright core. A mag 13-13.5 star is at the northwest edge and a mag 14 star is at the south edge. Roughly a dozen stars are resolved in total. A mag 10.8 star is 1.5' NNW and a mag 12 star is 1' SSW. Forms a striking double cluster with NGC 2137 1.4' NE (the two clusters form a gravitationally bound binary system). NGC 2125 lies 11' W and NGC 2150 (a galaxy) is 15' ESE.
