The 1892 and the 1895 are very similar. Also it was the basis for the Dutch 1895 which I used in my takedown project of a few years ago.
Dutch Takedown project
In fact the gun of subject in this, I used as a reference (at least pics of it) when I was planning and noodling on my project. I still have pics of it on my hard drive. I don't remember where I got them, maybe from a previous sale listing. Don't remember.
I don't think any serious mods other then the new bolt handle were done to the bolt. Mannlicher's just have the smoothest bolts ever and those who own them will a test to this fact.
I will be watching the sale and I couldn't even dare venture a guess at it's selling price. I won't be bidding, because I already have a takedown Mannlicher in 7x57. LOL smile
