Hi , toys from the attic . I remember getting this helicopter for " CHRISTMAS " in the late 60's while my brother was in Vietnam . I don't think I ever put battery's in it . It just sat on a shelf in my bedroom . I think their's a piece missing that goes on top of the main rotor . I know I saw it somewhere , if I find it I'll put it in an envelope and send it to you . The main rotor needs to be glued back on to the post that is there . " PLEASE " see the pictures and use the zoom feature , they'll show all defects on the unit . I don't know if it works . Being sold as broken for parts or repair . Sold as is no returns . Thanks .
