Here's some images captured off the internet, that show just the kind of combo pulley that my Stuart dynamo has mounted.

Note that one of the images in B&W looks to be an official ST catalog image.

It may be that the image you show has been turned down to the crowned wide flat belt configuration from the original pulley, or from stock material. Or perhaps the wide flat belt only pulley was an option as well?
