I just obtained this very old CCM bicycle from my father (see pictures below). This has been in the family for more than 60 years.
According to the information I obtained, it dates prior to the second world war. I could not find any serial number on it. I know that it was re-painted in the early 1970s. I have few questions:
1- What year does this model or style look like? 1940s or earlier?
2- The chain is pretty rusted. With a little WD40 I was able to get it flexing, but should I replace it? If so, with what type of chain?
3- I will try to keep that old-style seat. What should I use to clean the leather?
4- The handle bars and bottom bracket are a little tarnished. How should I go about rejuvenating these steel parts? Should I use some rotary sanding device to lightly sand or polish the metal?
5-What was the use of the vertical bars that are right in front of the handle bars?
6- Should I try to take apart the bottom bracket and head tube to clean or replace the bearings?
