Onya Mr RA for an excellent explanation.
I did not know about the windshield being fitted 'loose' in the 210.
However it does tell me why, in VH-KWW for example, the windscreen used to creak like crazy - especially on the descent, so I used to slow it down using the u/c method to keep it 'within my tolerances'.
But, alas, it was still full of 'internal' cracks which were a 'bugger' in the afternoon sun when landing to the west...
One 'famous' 210 driver in WA wrote this one up -
'Windscreen creaks badly on descent - frightens passengers - F#*in' TERRIFIES pilot!'
Cheers
