Help with maker's mark please - London 1937

This, to me, possibly looks like an overstamp of some sorts. It’s from the top of a glass sugar caster.
Grateful for any help.

I think it might just be what it appears to be: AJG. There seem to have been 3 attempts to get the mark stamped correctly and they have distorted the final result. I don’t unfortunately have any record of an AJG for this period.

Ok … many thanks
