Hallmarks-gold ring

[BsixThirteen]

Can anyone help me with these hallmarks? It’s on a 9ct gold ring. I’ve tried googling but not having much luck

ODI is maker’s mark. 375 means 9 carat gold in the UK as 37.5% gold. Anchor is Birmingham mark and V means 1995.

Are there any jewellery that could help with these hallmarks please? We are visiting from NZ and a family member gave this ring to us. They believe it is Georgian and whilst hallmarked around 1860, they think it may be earlier around 1810 due to who had it in their family.
We know the anchor means Birmingham but we can't find what the capital L stand for as Mr Google gives us multiple dates 😆
Any help would be much appreciated as it is so old NZ wouldn't have experienced jewellery in my area.

Is L the L for London the assay office.

Pictures aren't very clear.
