Vintage Brass Planter with Handles by Laurence Butler Cornwall, possibly from 1970's

the planter stands just over 11 cm high, diameter 19-20 cm (not a perfect circle)
relatively heavy, it weighs 0.718 kg 
the bottom is not brass, it's probably tin (however not 100% sure)

condition: polished but there many dark marks left (difficult to clean, please see all photos), slight deformation at the joint (photo 5), general wear/scratches, please all photographs as these are an important part of description

any questions please ask
thank you for looking
