Vehicle registration plate

[lancslassie]

Hi everyone, I have discovered a vehicle registration plate buried in my garden & I am intrigued as to its history. I know the number has been assigned more recently to a car, but wonder about the origins of it? Tried Mr Google & still unsure. It is a square metal plate GCC 123
Any experts in the motoring field that could help please?
Thanks, lancslassie

Some information on these sites:

Looks like the number was originally issued in Caernarvonshire, some time after Dec 1958. I don't know if there's anything online about what the vehicle was, but Gwynedd Archives seems to have records (see the second link).

I suspect it is the rear number plate off of a motorcycle

Could be, but doesn't have to be. Cars used to have square rear plates, too.
