SJK/Diamond Free brochures

I have tried to find some SJK (Suzuki) Diamond Free brochures to show on this page. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

1953 SJK/Colleda Duamond Free brochure from Japan (single page). Click to enlarge. The Diamond Free was a 60cc 2-stroke single-cylinder engine that was mounted on a standard bicycle frame. It was designed under basically the same concept as its precessor, the 36cc Power Free engine. The sales of the Diamond Free auxiliary bicycle engine reached 6,000 units per month in Japan. I managed to find a photo of this very early brochure from time before Suzuki Jidosha Kogyo made complete motorcycles. After some tweaking I managed to make a really decent image of it. The flip side of the leaflet was a blank page with no printing.
