I was given a pair of Bayonets today and was told they were WW I British. A bit of digging and they seem to be 1907 RSAF. They are quite worn and I can't see any makers stampings on them. The frogs are missing from both as well.
They would have clipped into the Lee Enfield .303, we used to use them as training rifles in Cadets. I remember them being massively heavy.
