So I was very lucky...
I had 3 pcs from AGR - one hunter



and 2 slipjoints something like Carl Schlieper Solingen
model Sodbuster, but China or Taiwan (I do not remember exactly).

The screws really seem outwardly weak,
but it will only show in the exploitation,
unfortunately, since my Chinook II also does
not seem to have the biggest screws,
but it is very durable
