Morris Minor Owners Club

WSL 179 - I recently bought this car with this 'age related' DVLA number, which I have now replaced with the period Bournemouth number 4862 RU, reflecting those I saw around me when I was young, and bought my first Minor, Black with red interior like this one.

Does anyone know what the original number of WSL 179 was, or if it is possible to find out from records held somewhere?

See my topic here from a few months ago.
It's possible to get the info from DVLA, but not easy: viewtopic.php?f=1&t=68615
