Thank you all for your well considered opinions. Very much appreciated you took the time to discuss the subject of crosswind limits.
Interestingly, I found myself browsing through my various RAF and RAAF Pilot's Notes of wartime types. In all those documents e.g Mosquito, Beaufighter, Lincoln, Dakota, Tiger Moth, B17 Flying Fortress and others there was no mention of crosswind limits. Seems you found out the crosswind limit by default although by then you probably had a ground loop on your hands
