I don't know the age. I suspect that it's new old stock as that specific impeller being Sherwood B isn't currently available. My best guess is that the rubber has "aged" and fallen to pieces with some work. Although I have an unused Sherwood B impeller in hand, I'm not game to use it. I have a brand new impeller from Cassell on the way.

Yes, the old how long has this "rubber" been stored saga. Sure can get you into hot water

Yes agreed guys, rubber is not good with aging even if unused.
It will soon return to it's natural state.
Brand new (fresh) best way to go
