This form was more or less faithful to the German design but added a barrel jacket for strength. Mauser manufacturing hubs were eventually established in several other countries including Belgium which begat allows for production of the slightly altered Model 1889 'Belgian Mauser'. If a given bolt-action rifle wasn't a Mauser-based design then it held origins in the competing Austro-Hungarian Mannlicher line of gunes. Once perfected beyond their early offerings, German Mauser bolt-action rifles proliferated the firearms market of the world by the end of the 1800s and into the early 1900s.
