Looks like T-RUCK got it in spite of the gloating

A buddy of mine also thought that this tool was for a very skinny tire, something in 1910-30's. I unfortunately I couldn't locate any makers marks.
So here is the next question...if all tires had tubes back then, why would a tire bead spreader be needed? I can see the need to spread a tubeless tire in order to patch it, but why the need to spread a tube style tire?
