Thanks for your efforts on the S.E.5a Nick. Hopefully something definite appears in due course,although the circumstantial evidence you have provided about the locationand hence possible unit seems pretty convincing.
Now a photo of R.E.8 A3880, I've a feeling that the photo is a reproduction,but new to myself in any case. Could someone provide the identity of the unit of this machine bearing a soon to become fashionable emblem?
