I bought a large box full of these wheels at auction a number of years ago, I was told they came from the floor of an old 1950s factory which made toy wheels, many still have there original axels attached.  This auction is for a "random" lot of 50 wheels and attached axles as shown in the first picture.  You "will" receive a random sample of the wheels shown above, all lots are about the same. There are three sizes of wheels, you will receive whatever happens to be in the lot of 50 you purchase, the axles are the same way. 

 I'm sorry that I had to increase the shipping cost, I was loosing $1.50 every time I shipped
