hmm. I think it might be a concert. maybe a super soprano, maybe a tenor. there are 17 frets on it so i dont really know. usually tenors have 17 to 19 frets. also look at the headstock. almost every make of ukulele company has a different headstock design. look at it then go to the "ukulele p***" thread here on UU. search through the different makes and you will find one that i similar.
