This is the like the first large rocket I started on when I got my first shipment of rockets from Estes... It was 4 rockets that I ordered....The Ventris, the Argent, the Partizon and the Solar Warrior...like forever ago..... ANYWAY...does anyone have any tips for making up "serial numbers" and "nuclear warning signs" in a military fashion to a "nuclear device" (NOTICE QUOTIAN MARKS) that has never been invented yet... I've done many net searches but haven't really "found" what I was looking for...I don't understand what the numbers mean... I found the standard "Radio-Active" warning signs which I will incorporate... But its the military numbering that I'm looking for. Here's what I'm working with... The green part is the "nuclear payload".... Any advice would be much appreciated.... THANKS!!!
