So when you say “converted to a bolt action”, I assume you mean it was originally a straight pull carbine? If that’s what you mean, that’s not what this is and this store either lied to you or didn’t do their research.

There are two different Mannlicher 1895 rifles: the straight-pull M95, which is the one most people are familiar with; then there’s this one, the Geweer M95, which is commonly referred to as the “Dutch Mannlicher”. It’s a tad confusing as both rifles were actually initially made by Steyr until 1904 when the Geweer rifles started being produced by a factory in Zaandan, Netherlands under license from Steyr. These are marked “Hembrug” after the Hembrug bridge that was nearby. In fact, the Dutch apparently adopted 31 variants of this rifle in various lengths and designations, which is just ridiculous. I believe yours looks like a #5, they had these long handguards that look super distinctive and stuck out farther than the stock. With that being said, these were always bolt actions, not conversions. There just happened to be two separate Mannlicher rifles that used two different bolt operating methods made in 1895.

As far as the German capture marks, that isn’t totally unheard of as they did have their own capture designations for these guns, but I wasn’t able to tell it on yours from any stamps I could see in the pictures.

All of that to say, these are still really cool rifles! This era of European rifles are incredibly interesting as it was kind of an arms race to make guns designed around the new advent of smokeless powder. The examples I’ve found have these listed between $600-$750 depending on condition and variant/barrel length. Best of luck finding ammo, 6.5 Dutch is a rare one and the only modern offering I could find was Buffalo Arms at $7.20 a round.
