These guns were have been made in 22RF, 25RF, or 32RF.  Extractors are different  height for each caliber, however it may be possible to alter the 22 (longest) to fit the others if  the width and hole are right.  

   Some of the early 1894's used the 1889 extractor. The intermediate 1894's had a wider top section than the bottom, this was originally  thought to be only on the larger calibers, but a couple of early 1894's  in 22RF have been located with a wide top also. 

   Confusion is compounded in factory illustrated parts catalogs, as depending on the vintage of the catalog the part numbers have also changed.   Also, in the deHaas books, his illustrations show a late ejector version 1894, which uses the 1915 extractor/ejector.  Also the numbers he uses are illustration numbers only,  not factory part numbers.

    Below is a compilation of MANY years of comparing different guns while manufacturing extractors while using a machinist's perspective of how the transitions played out.
