Around about 24,000 model 1892 rifles were made before the model 1896 replaced it in manufacture.  They made an effort to "upgrade" the model 1892 rifles to model 1896 standard and your rifle went through that process.  Part of that upgrade was replacing the rear sight and your rifle has the 1896 rear sight.  They also removed the under-stock cleaning rods and plugged the channel and your stock should show that.  Numbers of other bits were changed as part of that process and your rifle, again, shows bits of that.  In particular the receivers were "notched" for a hold-open pin on the extractor and the extractor itself received a pin.  Your rifle has that.

What's somewhat unusual is the number of 1892 parts your rifle retains.  Most of the bolt sleeve assembly is 1892 and that's somewhat unusual but seen in the wild.  The hand guard is also the model 1892 whereas most received the 1896 edition (goes back further in the back).

When the stock was cut down they didn't also cut down the barrel and that's a plus.

Nice gun but pity that stock cut.
