50s vintage Skotch tartanware plaid picnic set, tin hamper, cooler, jug

Skotch red tartan picnic set - a picnic tin 13 1/2" x 9 1/2" x 8 1/2" - a big cooler 11 1/2" in diameter x 15" in height - and an insulated 1 gallon glass jug with handle, 7" in diameter x 10".

All have been used and are suffering rust spots inside and out, as well as wear and scratching to the plaid finish. A good cleaning and a little light steel wool would proabably help a lot!
