60 MPH in an 85 year old Rolls Royce Phantom II

This was the first time we achieved 60mph in our 1933 Rolls Royce Phantom II, chassis Number 215AMS following a steering box rebuild, previous to this 40mph was the fastest speed before dangerous front wheel wobble was experienced. I think we could have easily pushed it above 60mph but the sun roof was held on with duct tape and it has a tendency to peel off is we go too fast.
