There was no "Steyr model 1898". I suspect your rifle being marked "Steyr 1898" on the left receiver wall, just like my G.Gibbs, Bristol & London, Mannlicher on a M95 (Dutch) action.

This is not a model designation, but the year of production.
The model designation was usually marked on the top of the receiver ring, but my Gibbs M95 lacks it too. On the other hand, my other early rifles are marked "Modell 1900" on receiver ring and "Steyr 1901" on sidewall, another one "Modell 1903" and "Steyr 1905".
All the clip loading, turnbolt Mannlichers, Romanian M92 and 93, Dutch M95 and Portuguese M96, use the same en-bloc clips.
