Scott thank for initiating this thread, but it will be a several weeks before my '36 Commander will be here and ready to post after detailing and upgrading chrome.
One bicycle I like to post is one from brwstrmgmt "basement dwellers" gallery page as it has the black/ivory color scheme I have only seen once (it is in the foreground
).
As to the rarity of the Commander series:
After searching ebay and CL for "Colson" one is likely to find relatively very few hits, mostly tricycles and after years of looking, it is hard not to come to the conclusion that Colson was a small shop operation producing less than it's contemporaries.
I would only consider the ribbed rainbow tank series "common" for its numerous years in prewar production and the fact that it was a base model for Firestone.
Also, distribution was also probably low as well and I do not believe the Firestone contract was inked in '36 for the Commander to have an appearance, so probably few outlets for sale.
Typically, to be truly "rare" there has to be low production, a short run as a single season, but also sales and survivability.
It would not surprise me if the '36 Commander was a sales flop being radically different from the norm, but also it was mentioned that these were $90 in another thread which seems to be a whopper of a price...maybe the cost of having to hire industrial designer Wilbur Henry Adams.
So this bicycle is truly rare by at least my definition, but probably for many reasons in supply/demand we are left to speculate.
