I've had the 'no notch' for a while... just found the 'single notch' last weekend... still cleaning it up... but was surprised to find the lodge logo... I thought the single notch was what they started using when they stopped putting the lodge name on them... but apparently they made at least one single notch with the Lodge name on it as well.
