Help Identifying Silver Hallmarks - Old Silver Spoon

Hi,

I would appreciate any help on identifying the marker’s mark and the possible date letter on this silver spoon I found. unfortunately, the spoon is quite worn and the hallmarks are not that visible. I have tried to identify the makers mark which I believe to be P C (but the C is a best quess), please see the photos.
I have tried all the usual websites and books I use to find maker’s mark but this time no luck!

If you have any info please help!!
Thanks,
Coin Collector
