A different engine perhaps?

Ah yes, it was. A Napier Lion V of 405 hp only – and it’s on floats. The UK service Ripons apparently had different engines to the Finnish examples. There is probably more similarity to the Blackburn Baffin which had the Pegasus engine (not sure which mark) and served in the UK Fleet Air Arm before being sold to New Zealand. We’ve not found the flight test reports for the Baffin yet.

Ideas welcome.
