Vintage but not Antique
by: Antique Jewellery

From how you describe you have:
Makers' Mark
next would be the assay office mark
then last would be the date letter

The crown mark was first used in 1975 so your piece will not be older than this but would need the other two marks to give a fully accurate date.

United Kingdom - European Union Member States Hallmark
by: Sean

These series of marks on your gold ring could be modern United Kingdom hallmarks. In 1973 a core group of European nations signed the Vienna Convention on the control of the fineness and the hallmarking of precious metal objects.

The United Kingdom is a contracting state member. There are certain guidelines to European Union Member States Hallmarks. The fineness of the metal is "375" which you have correctly ascertained is 9 carat gold. This mark is the "CCM" or Common Control Mark that verifies the metal's purity. The crown in a box next to the compulsory mark could be what's called the "Voluntary Mark". Hope this might help.
