The good thing about Wikis is that they often note their sources at the bottom of the pages... so the tfwiki just needs to note a source if they ever use the word "known".

I personally am one who thinks that the odds are, that after all this time, most are now lost, since we've heard generalised comments in the past that many older moulds are gone... but unless it is proven, we have to blindly assume that they still exist.
Well I fixed up it up to what we know from Botcon is lost. I fear that many moulds have been lost over the years myself. At least if they loose a modern mould they have the CAD designs to make a new one if it's an important/valuable mould.
