This mark (EC with a crowned chalice) was used from 1835 until 1867, when Callot formed a partnership with his son-in-law, Francois Auguste Boyer. The gothic "E" is a Belgian import mark used 1831-1869 to show that duty was paid on imported items, so it looks like this piece made its way from Paris to Belgium, likely not long after its manufacture.
