Old School Slots

Just found these sitting in a barn. Need cleaned up.
15 inch. Not sure of width, still have old tires on.
On the back there is a patent number, looked it up and they are from 1967.
5 x 4.5 bolt pattern
Looking for $300 OBO
Also have a pair of 14 inch slots that are 10 inches wide. That were sitting by these ones.
If interested asking $150.
Prefer local pick up.
