Terry Gambit vintage 12 speed. It comes with the rack, Cateye computer, spare tubes and clipless pedals if you want them.
The wheels are not original as I had new ones built some years ago. The cranks are Sugino and the derailer is Shimano, Diore I think. The bike will fit someone 4'10"-5'1" depending on your torso length.
I've got the same bike. It's a Gambit. Wonderfully fun bike. Yours may have an oval-ish shape sprocket that Shimanu tried. I understand that's fairly rare. I also believe tat the frame is hand-made in Japan. Good bargain for the price. Good luck selling.
