Thank you all for your kind suggestions about the pendant and the inscription.
There's no-one in the family tree with those initials - but I suspect that it is an individual rather than an organisation. Of course, I have absolutely no reason to support that
L.W.A's (Leopold Wilfrid Adams) history is a bit of a mystery - he died in 1933, long before my wife was born and she's anxious to find out more about him.
1913 was significant in that it was the year that his only child (my wife's father) was born. In 1911 at census time he was living with his grandmother in Folke, Dorset (the family were farmers) Later that year he married at Long Burton but was said to be living now at Okeford Fitzpaine.
When the birth of his son was registered he was living in Manston (Dorset). On all these occasions his occupation was given as 'Political Agent'
We know (from an engraved piece of silver plate given on his marriage) that he 'worked' for the Sturminster Newton Conservative Party. I've had no reply to the several enquiries I've made with them - actually with their latter counterparts (bet it'd be different if I'd have wanted to make a donation)
There's family rumour that later in life he worked for a motor dealer in Wooton Bassett - but that's a bit vague to follow up. He ended up in Coventry in the 1920/30's and we know a little bit more about that period.
Anyway, thanks once again for your suggestions - I'll have to hope more artefacts turn up which make it easier to piece together his history.
