Zowie! Those are neat conversions of military 1895 Mannlicher turn bolt rifles. Makes me think pretty hard about getting one of those fancy gunstocks. Mine is one of those odd Dutch carbines, made at Hembrug in 1917 and now painted black with some goop that looks as if it was left over from patching the leaks in the roof of the house trailer. I already have the little Lyman peep sight, along with all the case making stuff and 10 of the funny little clips. I'll do a quick accuracy test before proceeding. My carbine has a barrel that is only a smidge over 17" long and a sight radius of about 14", so I don't expect it to be a tack driver. I tend to think those rifles look better than they shoot.
