Help identifying a bicycle: Bridgestone 450

I have a Bridgestone bicycle that I would like to find more
information about. It is labeled as a "450 Racing Series" at
the top of the seat tube. It has a "Bridgestone Cro-Moly
Tubing" sticker near the bottom of the seat tube and a "Coca
Cola" sticker right under that. the only other markings are
a hand painted serial # on the BB shell.

I cant seem to find any references to a 450 line of
bridgestone bicycles on the web, only RB-1, RB-2, etc....
Any help would be appreciated.

Thanks Jason

Early '80s Bridgestones have spacey names like "Spica." Mid
80's road bikes had numbers. There was a child's-size ten-
speed called the "90." The cheapest adult road bike was the
"100," with stem shifting and no bottle braze-ons. I had a
blue one. The numbers and quality went up from there.

I've owned both a 400 and a 500, which at one point was the
cutoff between 27 1/4 wheels and 700c wheels. My 500 has
Shimano 600, my 400 had Suntour Cyclone. Most Bridgestones
of the era had metallic paint. I've seen silver, gray,
blue, and pink.

The RB nomenclature started ~89, I think. The iBob list
would have definitive answers for you:
