What BS stands for?
I just bought this bike. The frame is repaint so I don't know what bike is that. The head badge got the BS letters and I guess maybe it's a Bridgestone?
The derailleur is Suntour V-luxe.
Chainring is Sugino
Crank is Sugino Maxy

It is shipping to me now, the previous owner didn't have the picture. I had to make a quick decision when buy it. Now I have to guess what did I bought.

While that does not appear to be the typical Bridgestone head badge from the boom era, those do appear to be the faux spear point, die cast, Bridgestone lugs.
The large amount of chrome does point towards boom era (or pre-boom), as do the wing nuts. The V-Luxe derailleur did not come out until 1973. The cranks are actually Super Maxy which came out circa 1976, though the frame looks older. so it appears to be a frankenbike to some extent. I notice that it has the high front rack mounts typical of Eurasian models. The presence of stamped dropouts, top tube cable stops, die cast lugs and small diamter seatpost suggest an entry level model.
When the OP gets the bicycle, if it is Bridgestone, I can establish the year via the serial number.

Yes, it's definitely a Bridgestone and those are definitely the die cast aluminum lugs. Serial number, in conjunction with the components, would appear to indicate a 1975 model manufactured in late 1974. As stated earlier, it appears to be a Eurasian market model.

Looking good. 
That's what sold me on my Bottecchia, was the chromed lugs. It just looks very classy, I think.

The aluminum lugs were actually cast around the tubes, which had a flared end and plug. This allowed Bridgestone to join dissimilar and difficult to braze materials long before Raleigh's Technium process.

Thank you, I'm now looking for the front and rear rack for it. Because I want to use it as a touring bike to carry my large format camera equiptments.
While clean the Bottom Bracket, I found that the cup and cone BB nearly worn out. I want to replace it with the new BB but I don't know how to identify what exactly BB I need.
Could you please help me to solve it out?

The BB you have is probably English/ISO thread, with a 68mm shell width. You should be able to tell by comparing the cups with others you have lying around in English/ISO format, or you might take the cups to a local bicycle repair shop for an answer. The shell itself can be measured easily by examining the BB shell of the frame with a ruler. It's usually either 68mm or 73mm.
Assuming it's ISO - you should be able to replace the old BB set with any modern equivalent sealed-bearing unit (IRD or Tange cartridge types work well) of the same shell width and spindle width, which will ensure your Q-factor stays the same and your crank setup doesn't change.

Thank you Kunsunoke, I will try to measure the BB shell and spindle with. I have to do it myself cause the LBS in where I live they don't like to work with the old bikes.
