I have a red cover for the 505 but the bottom clippie thing is looser than original. I dropped the 505 one time and the clippie angled out a bit. It's still useable, the clippie is not broken, but you would need to be careful handling it. Or you can fix it, if you are inclined.
Free to a good home, all I ask is for postage, either first class or priority, your choice.
Please PM me if you have any interest!
