I have learned a lot from the guys there - some of them are real scholars on MS rifles. One of them has the full available history & the Mannlicher / Styre people use his services for research.

I have just bought a 1910 takedown rifle & am waiting to pay the full money & collect the rifle. It is a 9.5X57 (like all 1910s) & has a full length barrel. It is cased & the wood is quite exhotic but has no checkering! It has a tang pop up peep sight which is a top end feature. I am not sure if that was an English trade add on or an original Styer factory sight.

This is a photo of 1910 MS from H&H Mannhattan

I'll post pics of mine when I get it.

Does your rifle have a similar peep sights? Is the stock a full length Mannlicher stock with a muzzle cap? Good luck in your quest.
