Two of my father's uncles (brothers) enlisted with the RAF towards the end of WW1. I have managed to decipher the RFC/RAF unit codes for one brother but am running up against a wall with the second.
From other posts I have RD as Farnborough but are RD(D) and RD(R) also Farnborough?
The units I am struggling with are SYHC, 199YS, 200YS, E & PD Renfrew, IDE.
Marske and Eastchurch I understand but the service record is marked in red pen. Are these corrections / edits around the time of his discharge?
Many thanks in advance.
