1983 Hattori Sight

Found this unknown almost complete Bike in a local bike shop. I did some research on it and found it was a Japanese made Hattori Sight ( lower end of the Prosight) and the same bike frame is sold as a Shimano in Australia. Since I wasn't able to track down a set of the Hattori decals, I decided to build it as a Shimano. Using Shimano parts Cranks (Dura Ace), hubs, DX brakes set, DX seat post and pedals.  Overall its a fun build and loved the colour combo.  would appreciate any other information you might have on the Bike.
