ChiCom Advisor to North Vietnamese Army Photographs Lot of Four

Here is a lot of four original photographs depicting Chinese PLA advisors in North Vietnam or in send off ceremonies/about to leave for North Vietnam. As you can see, each Advisor is photographed with an NVA sun helmet. One photograph depicts the CHICOM advisor sitting next to what appears to be a destroyed radar. He is wearing an NVA Khaki uniform with a rare battle jacket style tunic As you may be aware, the Chinese sent in excess of 300,000 advisers to help north Vietnam with all aspects of their war. Many of the advisers actually made it down the Ho Chi Minh trail into Laos and Cambodia. There are many written reports about US units coming in contact with ChiCom advisors in the south. These photos are wallet size, about 1 1/2 inches square. Finding anything related to an actual ChiCom advisor is like finding a unicorn.
