Need help please

This is the stamp on an ornate knife, think I have figured out the first 2 but am really stumped on the third marking…thanks for any help you can give

It could be a Sheffield mark (crown + lion passant) and date letter, but I can’t work out what the date letter might be.

I have removed your other post under Photgraphing Silver so that any answers are in one place only.
