Thanks for looking Lustrousstone. Unfortunately, the link shows it saying "Blue Ribbon Glass" made in the USA. The chimney itself just says Blue Ribbon Brand, nothing about glass and nothing about its country of origin- which we can easily assume was indeed USA. I dont live too far from Ft. Collins, Colorado so I might drive up there when they open the museum in November. I have looked through the patents for that badge and couldnt find it. What is interesting to me is how it appears my wife's great grandparents seemed to have matched three different pieces together to make or keep the lamp working. Unlike today's disposable mindset. Regardless, thanks very much for the lead.
