It's hard to establish anything concrete about any given 92/96, as they - unabashedly - played musical chairs, and mix & match. There MIGHT be some clue in the manner in which the rod channel was filled (there are at least two such), but that would only date the stock.

FWIW, mine (6692) has the post-1901 split upper band, and the wide groove filler. It also has a [BA-WJ] cartouche, from Benicia Arsenal - whether this is related to the actual conversion is not known, but, from the band, it probably IS one of the later ones.
