Model numer 57-1401 (Sears Catalog Sales# 857-1401) was a guitar sold by Harmony in the mid 1970's through the early 1970's, and was basically a precursor and/or deluxe version of the H802. This version came in 2 variants, one with a vibrato unit, the other without. It seems the vibrato unit version is a bit more common. The one without uses the same bridge system as the H802 and 57-9568 models. Until I can get an actual Harmony model# on this one, the Sears stock# will remain the point of reference on this model
