My friends and I went and salvaged this important and rare equipment from a 1920's power plant in imminent threat of demolition that for the moment shall remained un-named. Under my care this equipment will not be destroyed or suffer the indignity of becoming living room curiosities.

I am always looking for more, especially the Thomson system family of instruments in the brass cases from the first era of power generation. I need a pen carriage and crossbar for the C4 as they were missing when I salvaged it. Contact me if you can be of assistance.
