I have this 15" wheel on my '50 model 3100, http://memimage.cardomain.com/ride_images/2/2877/4121/19692060190_large.jpg ,from what I've seen by looking at other wheels, the center section looks different, mine has 6 clips to hold the hubcap on, but once the hubcap is on, the contour of the wheel rolls out towards the outer part of the rim.

I've seen other wheels that look like these, http://memimage.cardomain.com/ride_images/2/2877/4121/19692060191_medium.jpg , which one is correct for a '50 model, what is the first wheel I posted from?

thanks for any help.
