Could someone :
Provide me with the name of the silversmith
Confirm that my reading of the other marks is correct :
84 in a square : essay mark (84 zolotniks)
A, a point, K, over "1850" : essay mark for Andrey Antonovich Kovalsky (Moscow, 1821-56), 1850 ?
Saint-George beating the dragon in a rectangle : mark for Moscow
AГ : unidentified silversmith
Thanks for your help !
