"...but my old Conn 12B (coprion), on the other hand, is like a tank."

Yeah, the inventor of the copper bell had no problem tempering the hell out of it. Conn Coprion bells can also be used as Sunday bars in a fight.

I have two horns (a trumpet and a cornet) with beadless, electroformed copper bells. They're both holding up fine, and seem no more prone to denting than brass bells. I owned and played a Schilke X4b for years, and that lightweight electroformed copper bell also held up well.

I have a Calicchio flugelhorn with a one-piece, hand-hammered pure copper bell, and it's pretty soft. I've been careful with that horn and have still picked up one ping and some ripples over the years.

I believe there is a huge difference between hand-hammered copper bells and electroformed copper (like coprion). My Conn trumpets with copper bells are seemingly undentable - and those were my road horns for a while, they took some serious abuse. Everyone I've known with, for instance, the Kanstul 1520, says it dents extremely easily. So I'd wager it has much to do with the difference between electroforming and hand-hammering.
