The 7 code is for 1830 NAS, 6 is 1833 NAS.
The deck pics give a good idea of how the aircraft looked at the time. Any ideas on how to do the over painted roundels? There's a clear colour contrast, would that be down to the difference between RN paint and the original US finish?
I have some small blue and white roundels from a Hurricane build, not sure they would be big enough but worth a look.
Albert Brown is 4th from left in the bottom picture. I have some others taken 24/1/45 when he was KIA during Op Meridian. Very poignant.
