Hi Matt,
I'm Johnny Clifford from the RAY Wyton Pathfinder Collection, home of the PFF. I've had a look for your dad and in the first instance he was posted to 97 Sqn from 9 Sqn in '43. He was posted from 97 Sqn to 635 Sqn on it's formation. I'm in the process of copying the ORBs for you and will get them to you ASAP. I've also had a look within the DFC award book and sadly it doesn't show his citation.
I'll be in touch ASAP
Cheers for now
Johnny
