Hallmark identification

I have a Christening set from Harrod’s and although I have managed to identify the actual maker (William Hutton & Sons) from the hallmark, I’m struggling on the rest.
Not sure if the Crown before Lion means it is Sheffield or not ? If I accept Sheffield then the date mark doesn’t seem to be in the correct font for only year with lower case N (1905) Anyone able to assist me please ?

Hi, the assay year is Sheffield 1930/31. Lower case ‘n’ also the punch shapes are consistent with that cycle (VII).
Hope this helps.

Great help, thanks Tony.
The year chart I was looking at only went up to 1916 and I wrongly assumed that they actually stopped issuing from then, silly boy.
