Jae,
I believe your aunt had a model 886 or 886F (the latter with the "Au-Toe-Matic" toe-touch height adjuster) from the 1991 to 1995 period (pre-1991 models would have a "baby blue" trim color similar to the 880), with the 6 amp motor.
Or, if it lacked the headlight, it would be a model 885 (1989 and early 1990 models have the 6-blade fan; models made since April 1990 have the 9-blade fan).
