This group of orders belonged to Cavalier of the Order of Labor Glory, Anatolii Nikolaievich Anfonkin.  His Third Class order was awarded in 1975, his Second in 1981, and his First Class was awarded in 1986, making him one of only 246 people who earned the title 'Cavalier of the Order of Labor Glory'. Forgive the small photos - this was one of my first groups, and at the time, I wasn't into thorough scans.
