Arioch , thanks for the pic
you beat me to it . not only are they bigger and more oval , the holes are closer to the outside ring . no matter which way you look at them , they should be oval . they also look to be a pain in the rear to put together
. they may look OK for those who have not been around them and not into the scale realism . As for price
as I thought not much different . for all practicality , a machined "aluminum" painted /powder coated is the best solution for this application . We're not hauling tons , just a few pounds if that . I can make them in steel if someone wanted but it would be made just as the real 1 is made just takes me more time . time = $
