What bayonet would be correct with my 1918 Lithgow SMLE

[old-smithy]

Especially th eOTC ones as it may be possible to go back and fidn out the original owner. I have one from a school that said that the cadet was presented with his blade when he left and they were intersted in havign mine as they had no example in their library, with the number they coudl have tracked who it was issued to and you coudl then possibly track down service records and flesh out the history of the blade at least till he parted with it. Unfortunatley i moved before I coudl visit th eschool, who the company I was workign with was workign for (2 losses as it was now a girls school! lol)
