V50 Engine Number

What format does the engine number take on my 1979 V50 please? From memory (as I am not near the bike as I write this) it seemed to have a ‘star’ at the beginning.

The reason I ask is that I need to inform DVLA that I have put a different engine in my frame…I didn’t think about taking the number of the previous V5 until too late…doh! As I have also changed the colour of the bike I want to make sure I get it all right when I send the V5 off with the changes on it.

Thanks

mine is :-* 5 digits * eg12345

Cheers Iain…got mine now…seems a very simplistic format which is why I was unsure.
