Re: Unmarked Columbia front mount ID?

The speed control/brake mechanism is the earlier style Columbia speed/brake mechanism, i.e. earlier than the Standard Model A. If I recall the Standard Model A in its first incarnation dates to about 1910, so this machine would probably be earlier than that, say ca. 1906-08.
Thinking some more about this. The crank escutcheon is a simple pressed-in ring similar to other early Columbia models like the AH and BI and AK. And like the even earlier cylinder models. Later Columbia models used an escutcheon plate fixed with two screws.
