Restored 1950's steel wheel roller skates

I am not sure if this even is at MOPAR events but on the British car side, we make valve cover racers. You take a valve cover, add a drive train and some weight and it is like a roller derby race ...but smaller :)

My drive train was made out of old roller skates like yours..

Here is a link to some pics..
