The CAA used to be quite prudish, I think they had a chap whose sole job was scrutinising the new allocations for "unsuitable" combinations.
There was a photo doing the rounds a few years ago of Terrier G-ARSL, its registration doctored with bits of black tape by the Rearsby apprentices. Dove G-ARSI suffered a similar fate. Its owner was so upset that he re-registered it.
The builder of a FW190 replica applied for G-FOCK. This was granted on condition that it did not appear on the aeroplane!
