IMHO Huvius' rifle is a typical Gibbs "old model" Mannlicher sporter. Gibbs imported these in military configuration and sporterized them. Those sold directly by Gibbs have the gibbs adress on the barrels, those retailed by others are often unsigned, but all carry a B-prefix serial number. My own three Gibbs Mannlichers show the same front sight base and many others I know share a distinctive stock style, resembling the Gibbs Farquarsons.

A Mannlicher B3085, dated "Steyr 1899", barrel signed by Gibbs.

A Modell 1900, B3452, dated "Steyr 1901" unsigned, retailer's # A808. Barreled action only salvaged from a junkpile, restocked by me, not yet checkered.

M 1903, B4842, dated "Steyr 1905", signed by Gibbs
