Yes your rifle probably started life as a model 1892. Production didn't start until 1894.
Early rifles were stamped with the year of production, 1894 is the year that the receiver was made. this ceased mid model 1896 production then the model was stamped on the receiver
Where did you get your serial number info?
Stock was probably switched during refurb. at some time in its life.
During production parts were placed in bins and pulled at random, "first one in last one out" nothing was done in perfect sequence. Slight over laps happen from time to time.
