Hello everyone. I saw this fan pop up on Ebay and since it was close-ish to me I made an offer and it was accepted. It's not in awful shape and is missing the shoulder screw for the oscillator and a couple screws in the gear box aren't original. My question is I when I took the fan apart to clean (It's CRUSTY) I found what looks to be a chip in the piece shown below. Is this a break or just a stop for the oscillator? It's not THAT major but I was unable to see from the picture online so I thought it was in working order and he didn't know much about it. It does work well and doesn't need much in the way of parts. 425 ain't cheap though haha..
