fine-camera-lenses Mount Ring information

I purchased this product assuming that I was going to buy a Canon EF 70-200mm f/4L USM lens which needed this collar. I was then persuaded to buy a 70-200mm f/2.8L lens which came with a Canon collar. So now I need to sell the Janco collar to some one who needs one.
However, I will say that comparing the Janco collar with the Canon collar is like comparing oranges to oranges. They are 99.9 percent identical.
The only thing I noticed when opening the package was, there were some minor nicks in the paint. Other than that, it’s a nice product.
