I believe this is a Sport SS model as from the remnants of the top tube sticker. This is a Japanese made Bianchi, and what should be the 2nd highest model in the Sport line up, coming in behind the Sport SX model. And according to Sheldon Brown,

While Bianchi is best known as an Italian brand, it was having bicycles built in Japan to its specifications for several years in the late 1980s. These were particularly nice bikes, with better workmanship than the Italian models.
Serial number is LS328488. Dunno what it means, but I do know its a 1983 bike(from component dates).
B panto and Ishiwata Magny tubing sticker. Nothing special about the tubing.
Discoloured(from metal pump clip corrosion?) seat tube Ishiwata sticker that says 'Guaranteed built with MAGNY Ishiwata. Double butted tubes, fork, & stays. This one also has Piaggio stickers, from the time when Piaggio owned Bianchi, which should be from 1980-86.
Kusuki Winpista bars(which were more comfy than Id though. I only use the Sakae Anatomic bars) with an odd 0.833 sized Sakae Custom stem. This stem actually is too skinny for the steerer. A standard 22.2 fits in perfectly, and Im not sure how the stem ever got put on this bike in the first place. Stem will be replaced with another Custom stem seeing that Ive got one in 22.2.
Seems like this bike was sold at some Bike n Hike store in California. Explains why the brakes were set up backwards to the Aussie set up.
Cool looking Sakae CR cranks with Sakae SP-153 pedals, and the Golden Arrow FD.
More Golden Arrow, the shifters. Friction shifting wasnt as hard as I thought itll be. Worked well enough for the hills around the North Sydney/Manly area.
RD and a hint of the Bianchi dropout
Non Golden Arrow brakes, but they work amazingly well, even with the original pads.
Anyway, the bike has been pulled apart, ready for cleaning and polishing. The bike will mainly remain the same, other than a correct fitting stem, different seat post and saddle, possibly a new headset, and the 27' Arayas will be replaced with spare 700c Open 4 CDs, as well as mudguards to fill in the empty space. This is one of the 6 bikes Im currently building, so it might take some time, but I should get it done by the end of the month, hopefully.
