I have just put a C30 funnel replacement for the just released Austrains C30 on my Signals Branch shop.
Available in either Frosted Ultra Detail or Frosted Extreme Detail.
This 3D printed funnel has no die join line and has the eight bolts around the flange to the boiler. It was designed to fit using an Austrains C30 engineering sample smoke box.

The funnel was designed from a NSWGR plan.
