1960 is a funny model year. I had always assumed that 1960 models had the '1958/59 post Oval' type of wing (ie: metal headlamp tube, unique pressing in the headlight bucket, same profile as late Oval wing).
Brown wing is Oval, Blue wing is '58/59 style' (note different pressing at the back of the headlight bowl).
However, I have owned three original 1960 model cars and two of them had the '58/59' style wings and one of them had the later 1961> profile wings. I thought that maybe they had just fitted later wings, but they were definitely original to the car and the inner wings had no holes for the headlamp tube mounting.
Check your inner wing (if it is original) and check for the headlamp tube mounting point adjacent to the headlamp bucket- you should see one hole about 20mm across and two smaller holes above and below the 20mm hole.
For reference:
58/59:
47 Beetle, 56 UK Karmann Cabriolet, 56 UK Beetle, 57 UK Type 2, 59 UK Beetle, 66 UK Fastback.
