This is another Rambler... mine is a 1933.
My 1940... it has seen a lot of modifications.
As far as value goes, old CCM's don't fetch very large sums... yet.
The Rambler was made for a very long period of time and were produced in very large numbers... very few changes were made in the design although some of the components were changed over time. My 1933 has a "Hercules" rear hub that says patents pending while later hubs read "CCM Hercules" and often have a date stamp on the actuator arm.
