Well I'm beginning to believe it is a '74 model built in '73! My Sugino crank arm is marked 48-5. If others are correct, this would translate to the fifth month of 1973 or May, 1973! My derailleur was introduced in '73. My wheel deflectors are marked "F & H 100 SAE A 73" (coincidence? I think not!). Why a '74 model? My Pro Compe freewheel came out in '74. I believe the 6 hole front derailleur came out in '74. I'm not sure if the the front post badging with the oriental font used in '74 was also used in '73 or '75. And I found the same bike with the same color scheme and the owner said his is a '74. Am I having fun yet? Yessss indeed! One more thing.....
I read that West Coast Cycles said the "KB" on the handle bars stood for "KB Bicycles or Kawamura Built". I think this was a marketing ploy! Back then the mindset was totally different than it is today. Automobile manufacturers thought that Americans would never buy Japanese automobiles because "American Made" stood for quality and Americans were very patriotic. Boy, were they wrong! But I digress. I was told that it stood for the all Japanese bicycle race that took place in Kobe, Japan. The "KB" stood for Kobe. And this manufacturer won and with it the bragging rights "Japan Champion". Anyway, that's my story and I'm sticking to it!
