hard to understand igorrock, does it mean you have such a thing on stock or it did not exist?

"The HORN Triggerguard pictured is exactly like what I was talking about. I was also thinking about something similar with Brass, Steel, or Iron, sorta reminiscent of 19th century muzzle loaders."

I am not sure with the Frühwirth rifle but the M 88 dont realy have a horn triggerguard. actually its a steal triggerguard with a seperate horn pistol grib. something you see very often on german guns betweenn 1870 and 1910.
