Daryl, if you were able compare the lid of the one for sale with another Red Indian quart you could see if they were similar or if there are any differences. The older cans usually had a single or double raised ring whereas the newer lids usually had more of a flatter style ring, though some didn't have any ring. You could also check to see that both lids on the quart are of a similar style. A different style on one end 'might' be a clue that the can has been re-lidded. I myself do not differentiate prices for cans whether they are full or empty. I buy and sell and collect cans, not the oil inside them. Great diagram Dick. Cheers, Don.
