if you desperately need to know, all the sqn records (F540s) should have been de-classified under the 30-year rule and should now be in the hands of the Public Records Office (or whatever they are called currently..), I know those for 120 and 42 were handled just so 'cos I did 'em! I think you can apply for them under FOI or somesuch - good luck mind as nobody seemed at all interested in taking them on when we tried to send them away!!!
