Following on from harveypj's comments - my July 1959 has the Hella lenses with the adjusters at 4 o'clock and 8 o'clock and they do have the VW logo at the top similar to the Bosch ones. My April 1960, on the other hand, has the Bosch headlights, so they were certainly fitting both types around this period. Both beetles are original cars so haven't had parts replaced, as far as I know.
The area of the bonnet where the VW badge sits is flat, not raised.
