Plated

The Celtic fringe of the BBC has been indulging itself. A Freedom of Information request has identified two "personalised" numberplates in the BBC's vehicle fleet.

402 BBC is on a Mercedes Sprinter Van, used by BBC Wales. "As this number plate was purchased around 15 years ago, detailed records relating to the transaction no longer exist, but it is understood that the cost was £300. The plate was purchased by BBC Wales (Resources) Ltd, a commercial operation which ceased to exist in 2001."

CU1792 - bear with me - is attached to a Mercedes Vito Traveliner Diesel 8 Seater in Northern Ireland. "To the best of our knowledge, this registration plate was assigned to a BBCNI vehicle at least 20 years ago. We do not hold any information about the purchase or transfer of this registration number".

This is where I need help - what am I meant to read into CU1792 ? 1792 was the first Belfast Harp Festival, and the year in which Catholics were allowed to practise as lawyers, and marry Protestants. I can't find a radio frequency which matches. Does it read as something in Gaelic ? Please tell me it's not staring me in the face....
