Ok good to hear. Wasn't sure if i was missing something there or not every other headstock i see has a round hole and a round wick. Does this one take a square wick? Was looking at the plate on the guard looks like the catalog number is 415-YA.
Nope - the wick will be round.
I had a 415-YA, SN was 85689. On the front of the headstock, there should be a very small hole, either just behind the oiler or above it. On yours, is that above or below the bearing split?
