Green or blue stamp of the double-headed eagle over 'Т-ва М.С. Кузнецова' with the factory town below (Dulyovo, Riga, Tver…). The eagle appears after the partnership won the state warrant in 1889; town names localise production and price.
The interlaced ЛФЗ monogram (Lomonosov Porcelain Factory) in underglaze blue, red or green; export pieces add 'Made in USSR' or 'Lomonosov Russia'. Colour and wording narrow the date: blue underglaze for everyday wares, red overglaze often on gift lines, 'USSR' vanishing after 1991.
Crossed swords in underglaze blue, taken from the Electoral Saxon arms. Sword form dates the piece: straight guards (18th c.), pommels (1763–74), star below (Marcolini, 1774–1814), dot between blades (1924–34). Strokes cut across the swords mark factory seconds.
