Mostly they've ground that stuff out and replaced with the current thermosetters. Looks like some of us have been killed ten times over and are here to tell about it. And on the lead balloon note, I accept that the stuff I'm seeing above the rattling shot is graphite lube but does anyone think like I do that a heavy element such as lead can be ground into a fine enuf flour to remain airborne long enuf to get a whiff? Remember I never said lead is lighter than air. Neither is wheat or corn until ground exceedingly fine. The paint mixer and wig powderer ailment suggests that lead dust do indeed "float".
