A kit from World War 2 that is more rare is the chalice kit. It has “wings” that open up. Here it is opened up and covered with a red velvet "vesperal cloth" that covers the altar mensa and linens when no in use.
“Portable altar with three panels that fold into a compact, fabric-lined carrying case with a leather strap handle. Used by Father George R. Metcalf of St. Paul, Minnesota. Metcalf served as chaplain for General George S. Patton during World War II. The style of the military uniforms depicted in the painting suggest that the altar was originally used during World War I” (In the collection of the Minnesota Historical Society).
