Hi folks -- I found this horn button at the Cars and Parts Swap Meet in Springfield, OH today. It has a Lucas marking on the back. From what car did this come from?
An answer from Society of Automotive History -- Britain webmaster Tom Clarke!!
That's an item made by Joseph Lucas Ltd. (now part of Goodrich, formerly TRW) for a British Austin/Morris car of roughly the late 1950s into the 1960s or so. It's probably an ox fording a river, hence the city of Oxford on the Thames and Isis rivers, and in turn the Morris Oxford car. I seem to remember such a button on Morris Minors too.
