Need help identifying ingot markings

British Silver Reading Silver Hallmarks

Hello Silver Collector,

I recently came into possession of a (presumably) sterling silver ingot pendant by way of my late grandmother, I’ve so far had no luck identifying the markings on the back and my Grandfather can’t recall where it came from. It doesn’t appear to be too old, but I know my grandparents were very well traveled so I’m really just hoping to find out where it came from so I can jog my grandfathers memory a little.

Any help identifying the markings would be greatly appreciated.

Thanks.

Could possibly be pewter marks.

Thanks for the insight Tomnik, that would explain why I haven’t been able to find anything so far, is there an easy way I can determine if it is pewter or not?
