Picked this up over the weekend, Wester Flyer head badged. I looked all over the frame for a serial but couldn't find one, maybe someone can help out. I took the rear and front hubs apart degreased and relubed the new departure model d hubs. The rear hub feels a bit stiff, not sure if that's normal for such an old bicycle. I usually ride a road bicycle so the hub feels smoother. I could be wrong. I noticed the front hub was a bit loose. Does anyone know if the front hub is missing lock nuts?(picture attached) Not sure if I want to leave the frame the way it is or maybe strip it down to bare metal and give it a ammonium chloride spray down. The bicycle has nice old wheels and original Wester Flyer tires, so I won't touch those.
