felice pappalardo fabricante di sprumenti a corda napoli 1890
Which Translates to,
Felice Pappalardo, stringed instruments maker. Neaples -1890 ('sprumenti a corda' litterally means instruments with strings; sprumenti is an ancient word of Neaples for the modern italian 'strumenti').
And Neaples has always been famous for its musical-instruments' craftsmen.
So i know the instrument is from 1890 as shown in the pictures also as it states in the guitar, and all this i found out online.
After searching and searching i came across an ebay listing, which had a picture of the guitar that i own, in slightly better condition, however the stamp inside is much diffrent, and this seller indicates that the guitar is signed, which mine also appears to be signed,
here is the link to this page, i think its very simular to mine and can help in determing the value and history of this instrument including its maker.
After countless hours of yet again searching.. i found through google image search a link to a museum website that had a simular looking mandolin and found out the the guitar also contains what is called "mother of pearls" hope this helps in helping someone help me with more information on this guitar thank you
