I got mine last year, from a old speed shop - new in the box wrapped in newspaper from 1971 - he couldn't believe someone still wanted to use one.

He actually had to go back and find a 1972 catalog to price it ! I tossed him a extra $30 on top for dinner as I was so happy to have it

He called it a "dual drive cable splitter" - Mine has Stewart -Warner stamped right into it.
