Thanks for the reply.
I did a little research and Berger is still in buisness, and are now known as Republic Storage Systems (http://republicstorage.com/about_republic_storage)
I also got this timeline from the net (http://glassian.org/Prism/Berger/index.html).
My guess is that they got out of the lantern buisness around the time of their first merger in 1921.

1888 - Incorporated as "Berger Manufacturing Company"
1900 - Moved to present Belden Avenue address in Canton (5 moves in 10 years)
