No, it looks like the bolt head on a new No4 Mk II I used to have - I know it was new because I took the mummy wrap, Cosmo, stores tag and paper wrap off it myself. I sold its twin to Riflechair about 15 years ago. This No 5 has zero wear and everything matches, the bayonet still has grease embedded in the handle screws. The previous owner managed a gun store from the 1970's to the mid 2000's. His collection was sold when he passed away, some of the things he had were incredibly rare - this was the one thing I could afford. 3 Long Branch laminates (one of each) 2 DCRA's, several C-Broad arrow No1 MkIII's etc. The gun I really wanted was a very nice Cavalry carbine with RCMP Boer War provenance - alas, way above budget. I think it looks a bit off in the photo because there's a thin film of grease on it.
