So it looks like a CSP but dosn't behave like one. Are you sure it is a CSP? And how do you tell the difference? (genuine question, not sarcastic.. just incase you start getting all spikey again...)

The spinner of the De Havilland (2-pitch or csp) and Rotol (csp) propeller look different.

still from 1940 newsreel showing a mixture of Rotol (recognisable by their blunt spinners) and de Havilland propellers employed on first-line Spitfires during the Battle.
