Thank you to those who have replied giving a choice between Grumman Avenger, Hellcat or Wildcat. Further information and photos have now appeared (you must understand that I am working at arms length on this).
My Father-in- Law was drafted to HMS Nairana in July 1944 until May 45. Nairana was launched in May 43 and was converted from a commercial ship into an escort carrier to be commissioned in Dec 43. She joined Russian convoy JW61 sailing on 20 Oct 44. At that time Nairana had 835 NAS aboard and was equipped with 14 Swordfish IIIs and 6 Wildcat VIs. This would seem to resolve the discussion and the crashing ac is a Wildcat. The censor on the back dates the 2 photos as 14 March 1945.
Other photos from the same draft are:
also dated 14 Mar 45
Comment on the back "HMS Nairana, Russian convoy, Most rough" Censor date 22 Mar 45
"Crashed on deck, Nairana 1945"
"and shipping off the Norwegian coast. Ranging the first strike, January 1945" but Censor dates it Feb 45.
As far as I can find out at present Nairana did 3 Russian convoys over this period. If anybody knows anything more I would be glad to hear.
