I have several (lots!) of NOS post-war litters with Civil Defence markings. I have a stencil to cover the bad stuff (:FCDA") so you can use them as late-war, or keep them rolled up and nobody will ever know. They are in Denver, CO and cheap to forum members - except shipping, which is always excessive.
