This unusual tank car transported vinegar for the Richter Vinegar Co. of Manitowoc, Wisconsin. The tank was built of redwood to resist the acidic action of vinegar, as steel would quickly corrode hauling such a commodity. The car has a capacity of 7,625 gallons and an unloaded weight of 50,300 lbs. General American Car Company built the car in 1929 for the Milwaukee Vinegar Works. It was leased to food producers so they could utilize it for long-term storage of vinegar without having to pay the railroads a demurrage charge. #11 served various companies over the years until it was outright acquired by Richter in 1957 from Jewett & Sherman Company of Milwaukee after their plant was destroyed by fire. In its final year, #11 sat at the Chicago Pickle Company’s Redgranite, Wisconsin plant before being retired
