Nice bow violin 4/4 Homa. Excellent condition, round baquete. Hair not have enough. I don't know what wood is. Hold perfect, the nail tightens perfectly. I don't know if silver or not. Frog is ebony wood probably. Have Roman Number VII stamped. Weight 54 G. Lenght 73 - 74 cm. Violins and bows described as 'certified' or 'attributed' include images of their certificates and are therefore considered to have a higher degree of documented certainty regarding maker, origin, and age than instruments described only as 'labelled' (violins) or 'stamped' (bows), for which we provide no guarantee of any kind
