Hello,
can anyone help identify silver spoon? Thank you in advance.
Regards

They look like the Madrid marks of 1764, but you'd better wait for confirmation from someone more knowledgeable than me.

Amena

More probably 1864

Hello friends, good afternoon. We have already talked about Espuñes and today it is Marquina. Named Angel Teresa Marquina, originally from Bilbao, she settled in Madrid in the mid-19th century. XIX, being one of the best chiselers of the time, becoming a silversmith to the Royal House. His solo brand is very scarce (AT/MARQUINA) and he almost always appears in association with other silversmiths, thus in 1852 he was working with Pedro Barrientos and in 1865 together with the Brothers Ramón and Francisco Espuñes, a union that began in 1859 until 1867. With Espuñes they made the famous "Columbus Tableware" for Queen Isabel II, preserved today as National Heritage.

Hola amigos, buenas tardes. De Espuñes ya hemos hablado y hoy nos toca Marquina. De nombre Angel Teresa Marquina, originario de Bilbao se estableció en Madrid a mediados del s. XIX, siendo uno de los mejores cinceladores del momento, llegando a ser platero de la Casa Real. Su marca en solitario es muy escasa (AT/MARQUINA) y casi siempre aparece en asociación con otros plateros, así en 1852 está trabajando con Pedro Barrientos y en 1865 junto con los Hermanos Ramón y Francisco Espuñes , unión que empezó en 1859 hasta 1867. Con Espuñes hicieron para la Reina Isabel II la famosa "Vajilla de Colón", conservada hoy en día como Patrimonio Nacional.
