Thanks. Think I’ll keep them for nostalgia reasons. The widow thought her husband bought the shells in the 50’s when he bought the Stevens 22-410. He kept the gun in a canvas carrier that looked like it was for an M1 carbine. Maybe I’ll see if I can find it and post a pic.The red and green boxes, introduced for the Remington Express in 1945 -- View attachment 61910 were pictured in the catalogs through 1962. They began being phased out as the plastic shells came in starting in 1961 in 12-gauge. By the 1963 catalog only the 28-gauge and .410-bore Remington Express remained in paper. By 1965, the .410-bore shells were in plastic hulls.
