Hi
L.8 on the BB, from what I understand, means the frame was built in 1988 (for the 8), and either December (L, 12th letter for 12th month), or the 2nd half of June (where each letter corresponds to the first 2 weeks or the last 2 weeks of every month).
I have 3 CDIs in original build. My cranks are Stronglight (France). I can't identify the make of your cranks, but they don't appear to be Stronglight and they are different to what appears on my bikes. The brakes and shifters are the same as what I have. If your bike colour (I believe they called it Burgundy or Burgundy red) doesn't exist in the US (which I believe BG alluded to in the past), then it's a Canadian market bike. I have the same one in 50 cm.
