Makers of cruciform bladed No. 4 MK. I bayonets?

[Enfieldlock]

I picked one up from a pile of junk at the War and Peace show. I was approached by some wannabe SS trooper who said it was no good as it had been messed about with. He did not have a clue about the Mark 1. He said it was mine for a fiver. Someone who walks around dressed like those thugs deserves no mercy, so I gave him the money and ran. It is pristine and genuine.
