How about more pictures? What advantages or disadvantages the design had?
I have some difficulties with pictures since my camera is broken. I have been using my cell phone camera, but as you can see the quality is poor.
M/34 was the last of these official "Experimental rifles". Because these rifles were official, the shooters could use them in competitions, where militrary rifles were normally used. In 1920ies the shooters were not satisfied with the m/91 and their ammo. You should remember, that by that time there were no new barreled m/91s and also the ammo was "Civil War Vintage".
The first ones were chambered for 7x57 and in the beginning normal iron sights with vindage adjustment were used. Later Lyman or Finnish equivalent aperture sights were used. By 1930 the caliber was changed to 762x54R. Some of the older types were rebarreled.
M/34 was produced at least by Tikkakoski.
