I used these on a Delica D5 before the full model change for one season. After removal, I cleaned, oiled, and applied silicone to the rubber parts, and stored them indoors. I think there is little deterioration. There are no major scratches or rust. There are small paint marks from when I took measurements. - Base: 415 x 3 - Hook: 041 x 4 - No instruction manual. I think the condition is good, but since they are used items, there are small scratches. Please understand. I will also sell each item separately, so please feel free to contact me.
