Hey, could someone tell me what model this iPod is? (Eng and Esp)

Eng: So I remembered my dad had this, and since I'm interested in old/retro things, I asked him if I could keep it and he said yes... but he doesn't know exactly what model it is, and he doesn't remember either. I also don't know if it needs a specific charger or if any old 30-pin charger is enough to charge it, so if anyone knows, I'd be grateful for your help :D

P.S.: My first language isn't English, and I used Google Translate to write this, so please excuse the spelling mistakes.

Esp: Asi que recorde que mi padre tenia esto, y al interesarme las cosas viejas/retro, le pregunte si podia quedarmelo y me dijo que si...pero no que modelo es exactamente y el tampoco lo recuerda y no se si necesita un cargador en especifico o cualquier antiguo cargador de 30 pines es suficiente para que admita cargaga asi que si alguien sabe estaria agradecido de que me ayude
