Hi -
this was an enamel cup made by the wellknown enamel maker Nikitin D. P. (ДÐ) in Moscow - in my opinion an original (enamel colours, technique, quality and style). Later somebody added the misfitting handle (enamel colour, technique and style) and the nonsense Fabergé mark and the sensless mark BA (Agafonov W.S.) of an other enamel maker. This destroyed an interesting object and made it absolute worthless.
Here the original marks from Nikitin D. P. for comparison:
