It came with two wheels and two of the black plates with axle pins. The picture that is being used here only shows one axle plate but the set did come with two.
Actually the picture even shows two of each. Well, it not exactly *shows* them, alas! Bad light conditions, sorry!
The second wheel is attached to the left side of the forge.
Back in those days they didn't leave their customers (us) with uneven numbers of necessarily paired parts.
This is just the sort of nonsense up with which I will not put.
