3.5 inches high/ 9 cms approximately 4 inches / 10cms diameter. Yellow lustre glaze gives this little hexagonal pot a high gloss finish turning the characteristic Aldermaston motif to an orangey brown . I believe the mark is for either Angela Monckton who was an apprentice at the Aldermaston pottery from 1972 to 1975 or Simon Middleton also an apprentice. The W is possibly the code for the glaze? in good condition. An accomplished little pot!
