The Spitfire "V", have sadly not been able to view it as a negative. However I put forward the following.
My thoughts are that this is a doctored version of "V ⊙ UZ", serial number R6770 of 306 Polish Squadron. Pilot became a POW, 22nd August 1942.
Two photo's of R6770 ( crash position very similar) can be viewed in the 306 Sqdn site in the Polish Squadron's Remembered website.
