I received a call from an older man that was looking for wheel parts and tailvane for a aermoter. I asked him what model it was he told me a 503 i told him it was a 502 aermoter didn't make a 503 but he insisted it was. Then he told me it has a ball bearing turntable with a fixed stem. I argued a bit but he insisted it was what he told me.has anyone ever heard of or seen one?

Is he referring to the hub (503) part # v. the gearbox #? Possibly a farmered 602 turntable? I’d like to see a photo.

Yes a picture would certainly help.

I talked to the farmer again he only has a landline so no pics but still insistes it's a 503 with ball bearings.i will try to see him sometime.

Interesting....
