Dad bought this as a new old stock from a bike shop here in the Philippines. It had Suntour derailleurs but generic shifters. The front derailleur spring broke whatever shifter it had. I doubt that it is a Haro because the long tube, between the seat tube and headset is straight and not the usual curved Haro.
