Using the emblem one each of the pieces of equipment I would say your items were made after 1960, possibly after 1970. The item on the left is a oil drain tank. The old oil would go down into a tank.
The item on the left is the pump to refill the oil. It also could have been used to refill transmissions, or differentials, of course not at the same time.
If you decide to sell these items they need to be posted in the Petro for sale with prices section.
