He has 2 No5 Bayonets. I am leaning towards the one with the knuckle guard. I was just wondering it was an actual thing or someone fantasy.

The second No5 has absolutely no markings so i am not sure if its genuine. I have read that it may be a sterling bayonet but from the research I have done, these typically didn't have the cross hole near the lock. It my be a replica but it is my understanding most are stamped RFI
