Nahverteidigungswaffe German WW2 Tank grenade launcher

This is a Nahverteidigungswaffe as used on many WW2 German tanks this is for an RC Sturmtiger tank but can be used for others.
The flair part is glued into the main part and I used a small peice of 3mm brass bar to insert into the hole in the flair part with a small ring made from copper wire soldered on to the end.
I also placed 4 small 14BA slotted cheese head screws in to the holes on the top of the main part to add more detail.
