Just reading about seats ...
My seat is covered with a heavy vinyl or maybe Naugahyde ? with not much padding .
I was wondering when Simplex made the change from leather .
Here's a few seat pics :
Obviously , I haven't cleaned it , yet .
Only a single nickle sized rust spot next to the rear bolt hole on the left in the pic .
And , this is the worst of it .
I also noticed that my tail light is period correct , but not Simplex correct .
