unidentified bowl copper/bronze? hand made?

[StargazeObama]

About 5 years ago I found this bowl at a car-boot sale and distinctly recall paying £2 for it, at first I thought the pattern was rolled onto the Metal and it was quite a new piece, but upon much closer inspection and curiosity of the markings no side is the same and has an uneven finish to the shapes, along with the indentations internally I now believe the entire pattern has been added by hand, the material appears to be bronze/copper but again I'm unsure and the markings on the base match nothing I was able to find after an hour of looking which is likely down to my lack of knowledge in the field. The pictures quite accurately show the colour.

Thanks for any help.
