The Davida "Pudding basin" Classic helmet? Very stylish and as you say, the Jeantet goggles look great with it.
I thought the bevel box issue had been sorted out by now.....the car I drove a year ago was very noisy and had its box changed by the factory later. They do settle down as they bed in though.
We like old planes on this forum as well......(trains, planes, watches, cameras etc etc!) so any photos will be very well received!!!!
