I am no expert on M assignments, so buyer please take note. I have four of these Locke Insulators. The two on the left each have a chip on an ear, while the two on the right have no damage. I am asking 5.00 each for the ones with damage, and 10.00 each for the ones that have no damage. Take all four for 25.00. These may have some scratches or scuffs, but nothing major. I will deliver these to Springfield on either Nov 1 or 2.
