Skill 5150 Circular Saw Brush Replacement, Running Intermittent, Made In America

I've had this saw since I was 15 years old. This was a low end saw when I bought it 30 years ago. It was all I could afford at the time. Its impossible to find a Circular saw made in America now. We need to bring are manufacturing back the USA. I purposely bought a saw in craigslist to find an American made saw.
