443 Squadron Spitfire

According to “RCAF Squarons and Aircraft” that 443 Squadron Spitfire serial number MK607 was coded 2I-S. this reference book has no pictures of that particular Spitfire but it seems to me that it would be standard markings for that period, I have a picture of a 443 Squdron Spitfire from that time period coded 2I-X serial MJ799 and it seems the same as any Spitfire from September 1944

The Squadron Commander of 443 S/L Art Sager passed away last Saturday at the age of 90 so I no longer have access to his log book for any further reference. Cheers
