A most unusual brush unit was this 1966 VW Beetle which was converted into a "brush buggy" capable of 100/55. I still have the Associated Press news article from 1973 featuring this unit and how it was built by then chief Carl Philabaum and the 30 members of the Valley Grove VFC, which is just east of Wheeling on US RT.40.
