Vacuum transfer valve for factory BOV/bypass valve

I have a genuine vacuum transfer/transmitting valve for the factory BOV/air-bypass valve for the 3SGTE. I bought a new one however the one I removed is in fair condition.

These are a small yet critical part of proper bypass valve operation.

The plastic nipples commonly break.

A couple of things re these:
-They are NOT the same as a one way valve
-they a difficult to find and surprisingly expensive (a quick google will confirm)

I'm in Sydney and being such a small/light part would be easy to post.

Open to offers, it's more that this will be helpful to someone.
