Older PSE bow and yes it is missing the string. Bow not worth a lot but would be a good bow to get you started into archery if you replace the string and nothing else is wrong with the bow. Economy string will cost around $15.00 and a good one around the $30.00 mark. Bow probably sold originally as a package deal since sight and arrow rest are PSE products. Cable slide needs to be moved up onto cable guard. Best advice would be to take it to an archery shop and have them look it over. Hard to evaluate from pictures.
