Frustrated with identification

[bytebit]

Hi there. Can you or someone you know who can help me identify some or all of the marks on the gold necklace pendant? I will appreciate any of your time with this important matter, David - from California, USA

Hi,



Your pendant was assayed at London in 1977. It is made of 9ct. gold. The maker, (AG), is unknown to me.
