I'll let you know when I find a good Turkish 652 for you. Red one was my first vacuum restoration, and I was lucky to find it in nice condition. I took off all the parts, cleaned it with warm water and soap using toothbrush, some rubbing compound to make it shine, greased the bearings, new belt and paper bag that's it. The second vacuum I restored recently (Hoover Junior Dirt Searcher) I only retrobrite the lens for light, used rubbing compound on base and handle, that was enough for me, it still looks kind of yellow but clean.
