I got these from a friend who was parting ways with a box of junk track, most of which was rusty and battered and broken. In it was these two rare, early Ives pull-cord switches! These were produced for only a couple years, the latest possible being 1912 but they were not cataloged for a couple of years near the end. I have added string to one to demonstrate it's use I hope to send these to someone who can restore them to their former glory.
