Old Silver Hallmarked Cutlery

Hi.

If anyone could tell me what these hallmarks from some old silver cutlery represent, I would be ever so grateful.

I recognise the Georgian monarch head and the lion passant, but am stumped with the rest!

Many thanks

Update:

(Having looked a little further, I am wondering if this is some kind of provincial Scottish mark?)

These are Sheffield hallmarks from 1819. On smaller pieces the crown and date letter were combined into a single punch from 1780 to 1853. AH is Aaron Hadfield.

Great, thanks!!!
