John Herschel recorded it as "very faint, pretty large, round; the first of a group of four nebulae with stars. (N.B. The mirror newly polished. See fig 20, Plate VI.)" The group consists of NGC 1962, 1965, 1966 and NGC 1970.
He notes that this could be Dunlop 136, which is either NGC 1962, 1965 or NGC 1970.
Recorded in "Observations of the Southern Nebulae made with the Great Melbourne Telescope".
See the discussion of Lithograph M.3.30 for the details.

Henize (Catalogues of Hydrogen Alpha Emission Stars and Nebulae in the Magellanic Clouds, Astrophysical Journal Supplement 2, 1956, p315) notes that his nebula LH N 120-144 "includes NGC 1962, NGC 1965 and NGC 1970." his nebula measures 8.8' x 8.0' (east-west by north-south), has a considerably irregular outline, is somewhat elongated and shows definite structural detail.
Shapley and Lindsay ("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) gives the size of the grouping as 3.4' x 3.4' and remark "bright loose stars in nebulosity."
The RNGC (Sulentic and Tifft 1973) notes that this is a 8.5 mag cluster+nebulosity in the LMC.
