I did do a flying course before whilst I was in the CCF Air Cadets. I flew about 10 hours and did a solo circuit, but I was 17 and silly/careless and lost the logbook
Sound like you did the ACPS with Tayside Aviation in Dundee. If so, you should be able to recover your hours if you speak nicely to them, because they keep and archive all the records (assuming they have not binned them all in advance of GDPR
)
No idea if these hours are any use these days (I'm long-since retired)...they used to be.
