I've been helping friend restore a nearly destroyed GEW '98 Efort 1907 rifle. The last piece missing is the bayo lug to fill the stock fiting, before we recreate a non functioning brass/bronze unit to fit the forestock space I'm wondering what was the original like? Is it the same or similar as K model then of course is it the short or long version. The rifle will never see a bayo and it may be more cost effective to cut/sand down a surplus lug.
