Shelter half tent stakes in CRAIG PICKRALL FIELD & PERSONAL GEAR SECTION Posted August 8 On 6/23/2013 at 8:31 PM, Keystone said: The "T" top aluminum pins from the Vietnam era were issued with specification JAN-P-501A dated 4 May 1949. I don't know when the color was changed but I have had original orange pins with a wrapper dated 1967. Hope this helps. Tim Keystone: I'd like to see the orange pins in a wrapper dated 1967. Can you post one?
