I'm also curious to see how you made out! is an interesting bike to say the least.
Thanks to this thread, I've found a photo of one bike made by a company I'd been curious about for a few years but never found anything other than a passing remark, the 'grand rapids bicycle company' (as far as I know absolutely no relation to the current LBS of the same name) on front (?) street here in GR, worked with the company that owned the building, but had never seen a photo of one of the bikes. A photo of a bike I assume was made there (

It's been something I was curious about for years, the building was not small in any way, two stories, and took up most of a city block, and had railroad spurs into it, so production HAD to be a fair size, but I had never seen one or even been able to find any real info on the company, And I live in GR!
