I recently purchased NOS inner and outer fenders for a 1955 chevy pickup. These all are in red primer which appears to be weathered and flakey. They also have no holes for emblems. Are these typical characteristics of nos fenders of that era?? I found reproductions in steel in California. Any idea how long steel reproductions have been out for?? I'm hoping these are not repro's but, I think were possibly used before. Any information would be greatly appreciated!!
