I Just dropped a video on my Youtube channel showcasing an original 1951 dated Accessory Packet Can for the C-4 Ration, Individual, Combat ration. I got it in the mail today and am super excited about it. I have been chasing one of these for years, and after a four week long negotiation with the seller, I finally nabbed it! I'll be doing a full video on the C-3 and C-4 Ration systems in the future now that I have a complete C-4 RIC and have enough information to reproduce the 1949 production C-3 RIC. That video will be fully scripted and detail the entire developmental history of the RIC from 1947-1952.
