Gold Wing, not Harley.
Still, very cool flaps. I have a pair of full sized mud flaps from my previous employer hanging on the wall of my shed. The place closed and I got a souvenir. 😎. Hope to put them on a future Stovebolt.
Progress was a truck tank and equipment manufacturer started in 1922. It survived the Great Depression, WWII, and the Recession of the 80's only to be swallowed up by a conglomerate and closed in 2009. I worked there for eight years. The Progress brand still exists and is currently owned by an equity company, but to my understanding they no longer manufacture their own tanks, but buy them from another manufacturer.
