Default 40 Bonnet

Post a picture - might help? Mine just opened bilaterally. Brilliant catch mechanism, by the way. There is slight negative pressure (uplift) over the rear of the bonnet visible in the windtunnel photos the Heritage Trust has. So the bonnet needs to be securely fastened flush.
My Touring 401 by the way was much less well engineered beneath its advanced, Milano crafted skin, with a pair of unsophisticated curved hooks either side to hold the hinged bonnet down, hence my losing the bonnet one night long ago on the M4, at 5000 rpm in 4th gear.
Dont go there...
