Alonso C. Merino was a contempory of Antonio Torres in Sevilla, but little is known about him. Two other guitars of his are known, both in Spain. According to Romanillos and Winspear, he first appears in the Sevilla's trade guides in 1895 at calle O'Donnell, 17. In 1897, he had moved from O'Donnell 17 down the street to no. 13. Because a year later he moved to No 18 O'Donell where he was listed until 1903, we can effectively date this guitar to 1897, as its label gives his address as "O'Donell 13 y Trajano 16."
