Service records for my grandfather

[nickgft]

GEORGE HENRY MARRATT transferred from the Army to the RFC on 15/8/1917, subsequently the RAF on 1/4/1918, then the RAF Reserve on 31/3/1919, finally "deemed" (?) discharged on 30/4/1920.
I have photocopies of these records - document number 92061, obtained from RAF service personnel records at Innsworth many years ago - (some details re units etc. not clear to read), BUT cannot find anything about him on here. And I know nothing and cannot find any details of his Army service prior to moving to the RFC. Even his name doesn't come up!!
Any advice would be gratefully received!

Hi

Find My Past has his service records (which it sounds like you have) and 1918 muster roll, there are no other records for him on there or Ancestry
Is there anything in his RAF service records that mentions previous army service.
