Antique Wine funnel

So I have looked all over the Internet for London date letters and I am still none the wiser as to what year this wine funnel was made.
This R looks considerably different to all the other ones that I have seen?

It’s 1812. Note that illustrations of hallmarks are always only going to be approximations as, for each year, there would have been a number of different punches in varying sizes and sometimes with slightly different outline shapes.

Yet again thank you for your help :blush:
