The doll's head rib extension is silver soldered on. I can attest to at least two that I know for sure were silver soldered. Two guns that "blew up"; one was the one Tom Armbrust, Sherman Bell and I (as an observer) blew up in the overload test. The other is a "long story" I won't go into. If the rib extension was soft soldered it would not add much strength. IMHO
