Can someone tell me the Axle-crown length on Raven-tour forks?

[retrodirect]

As the title says, can someone measure the Axle-crown length on their Raven-tour forks? no info anywhere on the Net.

Any help much appreciated

Owned a Raven tour which I sold, but wanting to get another set of the forks for a new bike, because they were darned lovely, but not sure between the replacement ones or the MT Tura (which are 430mm).
