The pump kit just arrived, hooray for Amazon Prime!

I'll upload pics of the rings, about all I can tell is that they're black...
The old rings that were in the pump are shiny all the way around...

How do you tell if they're cast or steel?

Sadly, the large metal sealing ring is broken, looks like the box got dropped and it cracked. Would it be ok to re-use the old sealing ring with a new o-ring?
