Don't throw away your money renting some cheap, no-name single horn while paying through the nose monthly for it! I hear that rentals are over $60 a month! This is a used Conn 4D single F horn. It's got perfect compression (0.1), comes with a mouthpiece and case and it's ready to go. Made of lacquered yellow brass it's in overall good condition. There are a few smaller dings and there is evidence of a repaired dent on the bottom of the horn - but that's all! Other than that it is ready to inspire a rising hornist.
