Here is mine. I use it all the time for my CVII meter and a 24mm finder. They line up fine with the picture frame. It pops off in two seconds for changing the film and is very secure. I never use the shoe on the edge. If I need a to use a VF and the meter at the same time, I use the double shoe adapter I bought from Stephen, our bartender.
I had three options with the bracket. 1) Make one as I did. Cheap, fast, and easy. 2) Make it where it attaches by a bolt into the threads that hold the flash sync port and bracket. That would entail a 5 minute episode every time I would rewind the film. 3) Spend $150-$250 on the Canon made bracket. I might have had to wait years for one!
I made the DIY adapter out of stock aluminum from the hardware store ($5), four #4 CS metal screws from the hardware store ($1),accessory shoe from the camera store ($7.95), and a flash adapter bracket from eBay ($10). I put felt on the bottom, even though it does not touch the camera top plate. It took about 2 hours of work. I also spent an extra unnecessary three hours color sanding and polishing the aluminum stock to make it shine like a mirror.
There is one Canon 7 flash adapter bracket for $9.90 now on eBay. A flash unit V will also work. They both can be found from $5 - $50.
