I pounded oakum last month!!
Well actually I pounded a bit of lead collar to tighten it all back up after a repair job,
but the oakum was underneath it and got mashed too.
I still have a little original cast iron drain pipe in my house.
Thanks for the picture Pritch.
I kind of have a thing for valve seat dressers, and that one is a beauty!
But the rarest, next to impossible things to get, in your picture are the lead molds.
Wrenches never die (well almost) and the chisels (punches, oakum tools, pick your name)
have to be intentionally harmed, with malicious forethought! They are very tough.
But anything can wreck those molds!
So there aren't many left at all.
