This small cannon is in the Sheldon Prairie Museum. It is a 12-pounder bronze mountain howitzer, M1835 cast at Cyrus Alger & Co. in 1837. There were formerly two of these in the town park, but one was stolen in the early 1970's never to be recovered. The final photo is of an old undated postcard showing both cannons. As a result of the theft, the remaining cannon is now in the museum but taken out and fired on special occasions. The carriage was built by a resident, Gerald Van Engen. Thanks to Museum Director Millie Vos for providing much information. The museum, south of the business district, is at 10th Street and 4th Avenue. The first photo was taken 4/23/08 - the second one 9/26/21. Thanks to Danny Krock for sending a copy of the postcard.
