The listing of 1960 service numbers jars rather with the fact that as a Craft Apprentice in the 202nd Entry RAF Halton Jan 65 my service number was initially 1960323 on joining Jan 5th '65, shortly after amended to have the letter " O " added as a prefix, shortly amended to have the letter "P " as a prefix as I presume the " O " could be mistaken for a zero.
I believe that the 201st entry started with 1960001 as without any fiddling or sleight of hand Apprentice Bond J of the 201st had the service number 1660007 to plague him for what I gather was a fairly short service career and who can blame him!
