Spitfire Tr.9

Can anyone help with this quest please?

I am looking for a set of Spitfire Tr.9 Pilots Notes to help a friend who is researching the type. Given the RAF never operated the marque there will not be an Air Ministry version. However given the Irish Air Corps did, were PNs issued by the IAC and if so can anyone advise where I might be ble to obtain photocopies or other such information please

Many thanks
