Ah, I thought it had the later type wipers.

Could well be one of the last 'clap hands' models - worth checking out the chassis number, to see how it compares to this:
October 1961
Flashing direction indicators incorporated into front and rear lamps.
Semaphore type direction indicators discontinued.
Glove compartment lid removed.
Windscreen washers fitted on De Luxe models.
Seatbelts anchorage points built into all models.
New range of colours and upholstery offered
Two-door saloon #925555, four-door saloon #925448, Convertible #947088, Traveller #925679
Is yours a 948cc or 1098cc?
