The yellow flag has blue stripes near its upper and lower edges and a central blue CK monogram, for Charles Kurz. Keystone Texas in March 2009 confirms a very narrow black funnel top, still narrower blue bands and their lower placement. A Great Lakes chart has a larger monogram and lighter blue. Rosanoski distinguishes the Key Lakes flag in Know Your Ships from the Great Lakes Fleet funnel on another page, identified as U228.
K95 is retained from Brown 1951.
