Your cart is a ERIE-MERIT S-165-R (also numbered 165-A-60RW), 1935, sixty gallon tank. My picture from 1935 shows it with small metal wheels. None of the pictures I have show that metal plate that is in front of the pump itself. Not much of my literature for this unit has a date on it, except for one which shows the unit still being offered in 1940. It also shows that the price for the unit was at one time was $50.00. This literature is for sale, just email me.
